If the edge length of a cube is 11 feet, what is the correct way to write the expression to represent the volume of the cube in exponential form?

(11 ft)³

Step-by-step explanation:

Given the shape is a cube, all of its sides are the same.

The formula for the volume of a cube is V = s³ where "s" represents the edge length.

Substitute "s" for 11 ft.

V = s³

V = (11 ft)³

In exponential form, do not solve for the volume. Leave the expression as

(11 ft)³

Without the units, the answer is 11³

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
