A box measures 20 inches wide by 14 inches deep. The height of the box is two feet. What is the volume of the box? Remember two feet would equal 24 inches.

6,720 inches or 560 feet

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
