Question

Simplifying Polynomials

5) What is the area of a rectangle with side lengths of 3x - 8 and x + 2?
A. 3x² – 2x – 16
B. 3x² + 14x – 16
C. 4x – 6
D. 4x + 10

Answer 1

A

Explanation:

Area of a rectangle =

`(3x - 8)(x + 2) = 3x {}^(2) + 6x - 8x - 16 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3x {}^(2) - 2x - 16`

Hence, we choose A.
