~NEED ASAP,PLEAASSSEE HELP<3~
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 (x - 7)2 represent?

Answer 1

(x + 1)(x - 7)^2 is the volume of EACH tank.

Answer 2

The volume of all the tanks

8 identical tanks
Volume of each tank; L*W*H = (x-7+8)(x-7)(x-7) = (x+1)(x-7)^2
so, for 8 tanks: 8(x+1)(x-7)^2

Answer 3

But What does the factor (x - 7)2 represent?

Answer 4

(x + 1)(x - 7)^2 is the volume of each
tank.

Answer 5

or easier to understand (x - 7)^2 is the volume of each
tank.

Answer 6

the options are:
A-The total base area of all the tanks

B-The total surface area of each tank

C-The area of the rectangular base of each tank

D-The area of a square shaped side of the tank

Answer 7

A-The total base area of all the tanks-Im not 100% sure
but this is my best educated guess, sorry. <3

Answer 8
