Answer & Step-by-step explanation:
Since you looking for the width and you are given the length and the area, then you will divide the area by the length.
(10x² + 5x) ÷ 5x
You can also turn this into a fraction so you can know what you are dividing.
So, your width is 2x + 1

Answer:
200.96 feet
Step-by-step explanation:
We have a pool with a radius of 28 feet.
They also tell us that there is a path around the pool and its width is 4 feet.
Thus:
The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
replacing
p = 2 * 3.14 * 32
p = 200.96 feet
therefore 200.96 feet are needed
40*7= 280
You would put 280 over 320
280
-----
320
Take off the zeros since they both have one.
28

32
28/32 is your answer.
If you need a simplified version your answer would be 7/8
This has to be done by hit and trial method. i.e. you have to checking adding which of the function from first column to function in second column will yield h(x).
The following functions yield given value of h(x).
f(x) = -2x + 3
g(x) = 7x - 9
f(x) + g(x) = -2x +3 + 7x - 9
f(x) + g(x) = 5x -6 = h(x)
So, from 1st column its the cell number 3, and from the second column its the cell number 2.
