Question

Which of the following represents the area of a rectangle whose length is 3x – 5 and whose width is

x-4

Answer 1

The area of a rectangle is width * length. What do you get when you multiply those two quantities?

Answer 2

20

Answer 3

Unless you have additional information (the value of x) that you didn't provide, that isn't the answer.

length = 3x-5
width = x-4

length * width = (3x-5)(x-4)

Answer 4

3x^2-17x+20
