Answer:
10 x^3 - x^2 - 29 x - 30 = (10 x + 9)(x^2 - x - 2) + -12
Step-by-step explanation:
Compute (10 x^3 - x^2 - 29 x - 30) ÷ (x^2 - x - 2) using polynomial long division:
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
To eliminate the leading term of the numerator, 10 x^3, multiply x^2 - x - 2 by 10 x to get 10 x^3 - 10 x^2 - 20 x. Write 10 x on top of the division bracket and subtract 10 x^3 - 10 x^2 - 20 x from 10 x^3 - x^2 - 29 x - 30 to get 9 x^2 - 9 x - 30:
| | | | | 10 x | |
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
| -(10 x^3 | - | 10 x^2 | - | 20 x) | |
| | | 9 x^2 | - | 9 x | - | 30
To eliminate the leading term of the remainder of the previous step, 9 x^2, multiply x^2 - x - 2 by 9 to get 9 x^2 - 9 x - 18. Write 9 on top of the division bracket and subtract 9 x^2 - 9 x - 18 from 9 x^2 - 9 x - 30 to get -12:
| | | | | 10 x | + | 9
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30
| -(10 x^3 | - | 10 x^2 | - | 20 x) | |
| | | 9 x^2 | - | 9 x | - | 30
| | | -(9 x^2 | - | 9 x | - | 18)
| | | | | | | -12
The quotient of (10 x^3 - x^2 - 29 x - 30)/(x^2 - x - 2) is the sum of the terms on top of the division bracket. The remainder is the expression that remains after the final subtraction step.
| | | | | 10 x | + | 9 | (quotient)
x^2 - x - 2 | 10 x^3 | - | x^2 | - | 29 x | - | 30 |
| -(10 x^3 | - | 10 x^2 | - | 20 x) | | |
| | | 9 x^2 | - | 9 x | - | 30 |
| | | -(9 x^2 | - | 9 x | - | 18) |
| | | | | | | -12 | (remainder) invisible comma
(10 x^3 - x^2 - 29 x - 30)/(x^2 - x - 2) = (10 x + 9) - 12/(x^2 - x - 2)
Write the result in quotient and remainder form:
Answer: 10 x^3 - x^2 - 29 x - 30 = (10 x + 9)(x^2 - x - 2) + -12

The difference of two numbers is 29. The largest number is 3 more than twice the smallest number. What are the two numbers?
Answer:
x + y = 29 equation 1
Five more than means add 5+5 three times the smaller number:
3x equals the larger number: = y 3x + 5 = y equation 2
From equation 1x + y = 29subtract x from both sidesy = 29 - x
We now have two things that are both equal tothe larger number y.
They must be equal to each other.
3x + 5 = 29 - x
Add x to both sides 3x + x + 5 = 29 - x + x4x + 5 = 29
subtract 5 from both sides 4x + 5 - 5 = 29 - 54x = 24
divide both sides by 44x/4 = 24/4x = 6
We now know x = 6
We also know y=29-x y = 29 - 6y = 23

The endpoints of YZ are Y(1, -6) and Z(-2, 8). Find the coordinates of the midpoint M.
Midpoint M
Find YZ. Round your answer to the nearest tenth if necessary.
[tex]~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ Y(\stackrel{x_1}{1}~,~\stackrel{y_1}{-6})\qquad Z(\stackrel{x_2}{-2}~,~\stackrel{y_2}{8}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -2 +1}{2}~~~ ,~~~ \cfrac{ 8 -6}{2} \right) \implies \left(\cfrac{ -1 }{2}~~~ ,~~~ \cfrac{ 2 }{2} \right)\implies \stackrel{\textit{\LARGE M}}{(-0.5~~,~~1)}[/tex]
The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.
We have,
To find the coordinates of the midpoint M of the line segment YZ, we can use the midpoint formula:
Midpoint M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)
Where (x₁, y₁) and (x₂, y₂) are the coordinates of the endpoints Y and Z, respectively.
Given:
Y(1, -6) and Z(-2, 8)
Now, apply the midpoint formula:
Midpoint M = ((1 + (-2)) / 2, (-6 + 8) / 2)
Midpoint M = (-1 / 2, 2 / 2)
Simplify:
Midpoint M = (-1/2, 1)
To find the length of YZ, we can use the distance formula:
Length of YZ = √[(x₂ - x₁)² + (y₂ - y₁)²]
Given:
Y(1, -6) and Z(-2, 8)
Now, apply the distance formula:
Length of YZ = √[(-2 - 1)² + (8 - (-6))²]
Length of YZ = √[(-3)² + (8 + 6)²]
Length of YZ = √[9 + 196]
Length of YZ = √205
Length of YZ ≈ 14.32 (rounded to the nearest tenth)
Thus,
The coordinates of the midpoint M are (-1/2, 1), and the length of YZ is approximately 14.32 units.

Solve the following radical equations.

The solution of the radical equation of x is 1.
A linear equation in one variable is an equation which can be represented in the form of ax+b where x is the variable and 'a' is the coefficient and 'b' is the two constants.
A radical equation is defined as an equation where the variable is under a radical or root.
We know that n-th root of a variable x can be written as x to the power of (1/n). Mathematically : [tex]\sqrt[n]{x} =x^{\frac{1}{n} }[/tex]
In the given equation:
∛x-1=√x-1
adding 1 to both sides we get:

- The flag of Equatorial Guinea contains an isosceles triangle.
(Recall that an isosceles triangle contains two angles with the
same measure.) If the measure of the third angle of the trian-
gle is 30° more than twice the measure of either of the other
two angles, find the measure of each angle of the triangle.
(Hint: Recall that the sum of the measures of the angles of a
triangle is 180°.)
Please show me step by step how you got the answer, Thanks
The measure of each angle of the triangle is 40°, 40° and 100°.
What is the triangle?
A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.Given:
In an isosceles triangle two of the three angles measure the same.
Let the two angles be equal to x.
The third angle is 20 more than twice the measure of either angle, which means 2x+20.
The angles of a triangle add up to 180 degrees.
(x)+(x)+(2x+20)=180
4x+20=180
4x=160
x=40 degrees
So, the two angles measure 40° each and the third angle would be,
2x+20
=2*40+20
=100°
Therefore, the measure of each angle of the triangle is 40°, 40° and 100°.

An alternate interior angle is one formed on the inside side of two parallel lines and opposite on the outer side of the transversal when those two parallel lines are intersected by a transversal and they are equal.
Alternate angles between a transverse and parallel lines are equal .
Here, the step 1 is correct :
as the sum of angles of a triangle is 180 degree therefore,
∠m +∠n + ∠o = 180°.............(1)
the step 2 is incorrect :
as angle o and angle p form supplementary angles not alternate interior angle therefore it will be :
∠o + ∠p = 180°........(2)

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
