Question

PLEASE HELP

A pet shop had 8 identical fish tanks in the shape of rectangular prisms. The width and height of each tank was (x - 7) inches and the length was 8 inches more than its width. The expression below shows the maximum amount of water which all the tanks together can hold:

8(x + 1)(x - 7)2

What does the factor 8(x + 1) represent?

The total height of all the tanks
The total length of all the tanks
The total volume of all the tanks
The total base area of all the tanks

Answer 1

x-7 is width

so x-7 +8 = x+1
is the length of 1 tank
