Question

Describe a situation with an output of area in square feet that can be modeled using the function f(x) = (2x+5)(3x).

Answer 1

A =
`6x^2 + 15x`

Explanation:

Multiply (2x+5) and (3x). To do that you must distribute the single term (3x) to (2x+5).

f(x) = (3x)(2x+5)

(3x)(2x) + (3x)(5)

6x^2 + 15x

It cannot be further simplified.
