B. (x - 8) feet

Step-by-step explanation:

Hence,length of the side of tae top = (x - 8) feet.

B  x-8

Step-by-step explanation:

x^2 -16x +64 = area of a square

We know that x^2 -16x +64 is the difference of squares

x^2 -16x+64 = (x-8)^2

The area of a square is given by

A = s^2

(x-8)^2 = s^2

Take the square root of each side

sqrt((x-8)^2) = sqrt(s^2)

x-8 = s

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

answer: 104.283185

step-by-step explanation:

3.14159265359 + 3.14159265359= 6.28318530718

since you're subtracting 3 twice, i'm just gonna say -6

6.28318530718 - 6 = 0.28318530718

0.28318530718 + 5 = 5.28318530718

5.28318530718 + 99 = 104.283185307
