Question

If the width of a rectangle is represented by 3x-5 and the length is represented by 4x-4, which expression represents the area of the rectangle?

Answer 1

A = 12x^2 - 32x + 20

Explanation:

The area of a rectangle of length L and width W is A = L*W.

Here the area is A = (3x - 5)(4x - 4) = 12x^2 -12x - 20x + 20, or

A = 12x^2 - 32x + 20.

Answer 2

7x-9

Explanation:

ignore this it is wrong my bad

adding like terms

3x+4x=7x
