Question

Samuel needs to mail a package to his friend in New York. He places an address label with the length represented by

the function l(x) = 3x

3 + 2x

2 − 4x + 5 and the width represented by the function w(x) = x + 2.


Part A: Find the area of the label.


Part B: Which of the following statements are true about the area of the label? Select ALL that apply.

 A(x) = l(x) + w(x)

 The resulting polynomial for A(x) will be a 4th degree polynomial

 l(x) =

A(x)

w(x)


 The resulting polynomial for A(x) will have a leading coefficient of 6

 A(x) = l(x) ∙ w(x)

 The resulting polynomial for A(x) will have a constant term of 10

Answer 1

The answers are

°the resulting polynomial for A(x) will be a 4th degree polynomial

°l(x)= a(x)/w(x)

°A(x)= l(x)·w(x)

I did the algebra CFU so trust me it's correct ;)
