Answer:
The answer to your question is the letter B. 20x² - 4x - 16
Step-by-step explanation:
Data
length = 5x + 4
width = 4x - 4
Formula
Area of a rectangle = length x width
Substitution
Area of a rectangle = (5x + 4)(4x - 4)
Expand
Area of a rectangle = 20x² - 20x + 16x - 16
Simplify like terms
Area of a rectangle = 20x² - 4x - 16
