Step-by-step explanation:
[tex]1 + 5a + 7a^{2}+a+3\\[/tex]
so you have [tex]7a^{2}[/tex]
5a + a = 6 a
and 1 + 3 = 4
Answer: [tex]7a^{2} + 6a + 4[/tex]
Answer:
7a² + 6a + 4
Step-by-step explanation:
Now we have to,
→ Simplify the given expression.
The expression is,
→ 1 + 5a + 7a² + a + 3
Let's simplify the expression,
→ 1 + 5a + 7a² + a + 3
→ 7a² + 5a + a + 1 + 3
→ (7a²) + (5a + a) + (1 + 3)
→ 7a² + (6a) + (4)
→ 7a² + 6a + 4
Hence, answer is 7a² + 6a + 4.

If a numberis divisible by two co-prime numbers then it is also divisibe by their product
It's true that co-prime number is divisible by their product.
Co-prime numbers are pairs of numbers that do not have any common factor other than 1.
e.g., ( 4,7), (2,3), (5,7,9) etc.
Let's take two co-prime numbers i.e., x and y i.e., (x, y)
The product of them is ( x × y)
Therefore,
x × y/ x = y ,and x × y/ y = x
Lets understand with an example,
Let's take two co-prime be (2,5), its product be 2×5 = 10
so when we divide product with the number i.e., 10/2=5 and 10/5=2 which is divisible.
Therefore the co-prime number is divisible by their product.

Find the value of x. helpp!!
Answer:
Step-by-step explanation:
s=180(8-2)
s=1080
So
106+(180-11x)+(180-12x)+143+(180-17x)+130+(180-12x)+137=1080
-52x=1080-1236

the question is "what is the rate of change of the average height in feet of the trees on the farm with respect to the number of years since the trees were planted"
please help!
Answer:
Rate Of Change= 7
Step-by-step explanation:
all you have to do is see the difference, imma make a table here first
x y
1 10
3 24
6 45
11 80
15 108
from 10 to 24 you add 14
from 1 to 3 you add 2
so y/x
14/ 2 = 7
check:
from 24 to 45 you add 21
from 3 to 6 you add 3
so y/x
21/3 = 7
From y/x your final answer will always be 7.
So the rate of change will be 7.

Write the Slope-Intercept and Point-Slope forms of the line passing through the point (-3, 2) and having a slope of -4/5
Answer:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]
Step-by-step explanation:
The slope-intercept form of a line is written as y = mx + b, where m is the slope and b is the y-intercept.
The point-slope form of a line is written as y - y1 = m(x - x1), where (x1, y1) is a given point and m is the slope.
Here, we see that the slope is -4/5, which means that m = -4/5. Since we're given a point (-3, 2), let's go ahead and just write the point-slope form already. (x1, y1) = (-3, 2) so x1 = -3 and y1 = 2. Then:
y - y1 = m(x - x1)
y - 2 = (-4/5) * (x + 3)
[tex]y-2=\frac{-4}{5} (x+3)[/tex]
Now, we want to find the slope-intercept form, so we need to figure out the y-intercept. Well, first, let's plug in what we know:
y = mx + b
y = (-4/5)x + b
Any point on this line will satisfy the above equation. Since (-3, 2) is on this line, if we plug -3 in for x and 2 in for y, the equation should hold true, so we can solve for b:
y = (-4/5)x + b
2 = (-4/5) * (-3) + b
2 = 12/5 + b
b = -2/5
So, the y-intercept is -2/5. Then the slope-intercept form is:
[tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
Thus, our two equations are:
slope-intercept: [tex]y=\frac{-4}{5} x-\frac{2}{5}[/tex]
point-slope: [tex]y-2=\frac{-4}{5} (x+3)[/tex]

What is algebraic operations?Algebraic operation is any one of the common operations of arithmetic, Which include addition, subtraction, multiplication, division, raising to a Whole number power, and taking roots (fractional power). These Procedures could be applied to numerical data, in which case they are Frequently referred to as arithmetic operations. Similar operations can be Carried out on variables, algebraic expressions, and, more generally, on Components of algebraic structures like groups and fields. A Mathematical operation could also be defined simply as a function from a Cartesian power of a set to the same set.
Given that:school uses 13,470 pieces of white paper, 7,970 fewer pieces of blue paper than white paper, and 2,400 fewer pieces of yellow paper than blue paper.
The school uses 22,070 pieces of paper in all.
IT is already given that the school uses 13,470 pieces of white paper. Then it says that there are 7,970 fewer pieces of blue paper than white Paper. So if you subtract 7,970 from 13,470, you get that the school used 5,500 pieces of blue paper. Then it says that there are 2,400 fewer Pieces of yellow paper than blue paper. So when you subtract 2,400 From 5,500, you get that the school used 3,100 pieces of yellow paper. So if you do 13,470+5,500+3,100, you get that the school used 22,070 Pieces of paper in total.

at a popular night club, the ratio of women to men is 20:11. if 7 men arrived to the club, the ratio would be 3:2. how many men are currently at the party?
Before there were 33 men and then 7 men arrive total men are 40.
• In mathematics, ratio is an ordered pair of numbers x and y, written x/y where value of y is not equal to 0. A proportion is an equation In which two ratios are made equal to each other.
Since the initial ratio is 20 : 11,
Lets assume there are 20x women and then the number of men will be 11x.
If 7 men arrive more the ratio will become 3 : 2
20x / (11x + 7 ) = 3/2
40x = 33x + 21
7x = 21
x = 3
Initial men = 11x = 11(3) = 33
When 7 more men arrive , total men = 33 + 7 = 40
Before there were 33 men and then 7 men arrive total men are 40.
