Answer:
2x*-3x-5
* = squared
Step-by-step explanation:
step 1: distribute “x” to “2x+1”
-you now have the equation: 2x*+1x-4x-5
step 2: combine like terms (combine “1x” and “-4x”. that gets you “-3x”.)
-you now have the equation: 2x*-3x-5
step 3: you have no more like terms, your equation is solved.

I need Area of Base
height and
Volume
Area of base = 52
height = 5
Volume = 260
To find the volume of a rectangular prism all you need to do is multiply the length * width * height.
the area of base is the length * width = 13 * 4 = 52

Determine whether each function is an example of exponential growth or decay. Then find the y -intercept.
y=100(0.25) x
The function y = 100 ( 0.25 ) ˣ is an exponential decay function.
An exponential function is defined as y = a ˣ where x is a variable, and a is a constant called the base of the function.
We are given a function:
y = 100 ( 0.25 ) ˣ
We need to tell whether is is a exponential growth or decay function.
We can see that the value of a ˣ = (0.25) ˣ
So, the value of a = 0.25.
Since, it is a decimal and not an integer, its value will decrease with the increase in exponent x.
So, it will be a exponential decay function.
Therefore, we get that, the function y = 100 ( 0.25 ) ˣ is an exponential decay function.

Use the gcf of 48 and 30 to write the sum of the two numbers as the product of their gcf and another sum
Answer:
The resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.
Step-by-step explanation:
It is given that the GCF of 48 and 30 to write the sum of the two numbers as the product of their GCF and another sum.
Now,
The largest number that can divide two numbers is known as the GCF. The formula for 48 plus 30 is as follows;
=> 48 + 30
=> 6 (8 + 5)
=> 6 (13)
=> 78
Here, the numbers are given as 48 and 30 so, the expression is;
=> 48 + 30
And their GCF is 6 so, we get;
=> 48 + 30 = 6 × 8 + 6 × 5
=> 48 + 30 = 6 (8 + 5)
=> 48 + 30 = 6 (13)
=> 48 + 30 = 78
Therefore, the resultant expression is 48 + 30 = 6 (8 + 5) = 6 (13) = 78.

Jeffery will obtain $54 as interest on $4,500.00
What do we mean by interest?In finance and economics, interest is the payment of an amount above the repayment of the principal sum (that is, the amount borrowed) by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by borrower or deposit-taking financial institution. It differs from a fee that the borrower may pay to the lender or a third party. It is also distinct from a dividend, which is paid by a company to its shareholders (owners) from its profit or reserve, but not at a fixed rate, but rather on a pro-rata basis as a share of the reward gained by risk-taking entrepreneurs when revenue exceeds total costs.If Jeffery originally invested $4,500.00.
Then, 1.2% interest on 4,500.00 will be:

What are angles <6 and <12?An interior angle is an angle that is inside a shape. It can also be described as an angle that lie in the area bounded between two parallel lines that are intersected by a transversal. In the given image, angles 6 and 11 are interior angles. The sum of interior angles is 180 degrees.

Given the linear function f(x) = −4x 8, what is the value of x if f(x) = 24? x = 104 x = −4 x = −8 x = −88
The value of x = -4
The given linear function is f(x) = -4x+8
We have to find the x corresponding to f(x) = 24
For our convenience, let f(x) = y
Then y = -4x + 8
This equation implies y in terms of x.
Isolating x to one side of the equation, we get,
x = (y - 8)/-4 = (8-y)/4
This equation gives x in terms of y.
So when f(x) = y = 24,
x = (8-24)/4
⇒ x = -4

Evaluate each expression for x=-2,0 , and 2 .
10x⁺¹
The value of given expression for x=0 is 0, x=-2 is -20 and x=2 is 20.
Given the expression is (10x)⁺¹.
Firstly, we will simplify the given expression (10x)⁺¹ for x=0.
Substitute the value x=0 in given expression, we get
(10x)⁺¹=(10×0)⁺¹
As we know that something multiply to zero is 0.
So, we get
(10x)⁺¹=0
Now, we will simplify the given expression (10x)⁺¹ for x=-2.
Substitute the value x=2 in given expression, we get
(10x)⁺¹=(10×2)⁺¹
Now, we will know that if we multiply any number with 2 we get twice of it, we get
(10x)⁺¹=(20)⁺¹
(10x)⁺¹=20
Furthermore, we will simplify the given expression for x=-2.
Substitute the value x=-2 in given expression, we get
(10x)⁺¹=(10×(-2))⁺¹
Now, we will know that if we multiply any number with 2 we get twice of it, we get
(10x)⁺¹=(-20)⁺¹
(10x)⁺¹=-20
Hence, the value of expression (10x)⁺¹ for x=0, 2 and -2 is 0, 20 and -20.

Simplify each expression. x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂
The expression can be simplified through division of the exponential (power).
In the given expression, if the powers have the same base, we can actually divide the power. In order to carry out the division of the exponential (power), we can subtract their exponential.
In the general form, a-m=1/am
As there are two different base terms x and y in the numerator and denominator, we will subtract the powers of x terms and powers of y terms.
Let us simplify the x terms,
x¹/₂÷x³/₄=x(1/2)-(3/4)
Solving the powers,(½)–(¾)=(2/4)–(¾)=(2-3)/4=-1/4
x¹/₂÷ x³/₄=x(1/2)-(3/4)= x-1/4
Let us simplify the y terms,
y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)
Solving the powers, (-1/3)-(1/2)=(-2/6)-(3/6)=-5/6
y⁻¹/₃÷y¹/₂= y(⁻¹/₃)-(¹/₂)=y-5/6
Putting the terms together gives us,
x-1/4 *y-5/6
It can be expressed as a fraction as a-m=1/am
x-1/4 *y-5/6=1/x1/4y5/6
Hence, x¹/₂ y⁻¹/₃ / x³/₄ y¹/₂= x-1/4 *y-5/6=1/x1/4y5/6

Find all values of for which the rocket's height is 29 meters.
The values of for which the rocket's height is 29 meters are 0.75 and -0.67.
What is a velocity?Velocity can be described as a vector quantity having both direction and magnitude which is the distance traveled per time.
We were given the rocket's height h as [tex]h=57t-5t^2[/tex] which is an equation, and we were been given the height which is the value that can be input into the equation as is 29 meters , then we can proceed to simplify the equation as

per the laws of intersecting lines the angles on one side of any of the lines must be the same as the angles on the other side of that line - just left-right mirrored.
for that reason, CGE = DGF.
also to remember : the sum of all angles around a point on one side of a line is always 180° (because they represent a half-circle with that point being the center). in other words, these angles are supplementary (together 180°).
therefore,

A company stock was selling at 28$ a share. A month later, it was selling at 21$ a share what is the percentage loss
The percentage loss is 25 %.
Percent change is the difference between subtracting the old value from the new value, dividing by the old value, and multiplying the final result by 100, expressed as a percentage. Generally, to convert a fraction to a percentage, multiply by 100. Similarly, the fraction (ratio) of the amount difference from the initial value is multiplied by 100 to get the percentage change. The formula for the percentage change is defined as the ratio of the difference of final value and initial value to the initial value. The formula of percentage change is mathematically expressed as [tex]Percentage=\frac{Final - Initial}{Initial} \times100\\[/tex] ..(1)It is given that initial value of company stock is $28 and final value is $21 .

Write each expression as a single logarithm.

The expression as a single logarithm is log (2/3).
In mathematics, the inverse function of an exponent is a logarithm. This means that the logarithm of a fixed number, such as a, at base b, is used to represent the exponent to which the fixed number must be raised in order to create the number x.
The general properties of logarithm for a fixed base are:
logₐa=1logₐx+logₐy=logₐxylogₐx-logₐy=logₐ(x/y)logₐxⁿ=n logₐxlogₓy=(logₐy)/(logₐx)Now from the above properties of logarithms we can calculate:
log 8-2 log 6+log 3
=log 8 + log 3 - 2log6
We know that logₐx+logₐy=logₐxy and logₐxⁿ=n logₐx
∴log(8×3) -log(6²)
=log 24 - log 36
Again we know that logₐx-logₐy=logₐ(x/y)
=log(24/36)
=log(2/3)
Therefore the given expression written as a single logarithm is log(2/3).

standard formslope-intercept formpoint-slope form.The typical form of a line equation is ax + by = c, where a but rather b are the coefficients of variables x and y, respectively, as well as c is a constant if all possible values must be integers. In the meantime, the slope-intercept form is given by the formula y = mx + b, where m is the line's slope as well as b is the y-intercept. Given the slope m and a point on the line (x, y), we can formulate the equation using point-slope form, (y - y1) = m. (x - x1).
According to the given data:To build up the equation, use the point slope form and enter in the values.
(y - y1) = m(x - x1)
where;
m = 5/6
(x1 , y1) = (22 , 12)
(y - 12) = 5/6(x - 22)
In slope-intercept form, the equation of the line is:
(y - 12) = 5/6(x - 22)
y - 12 = 5/6 x - 110/6
y = 5/6 x - 19/3
In standard form, the equation of the line is:
y = 5/6 x - 19/3
5/6 x - y = 19/3
