If the area of a rectangle is (〖40x〗^2-6x-4) square feet, and its length is (3x – 5) feet, find the width.

Answer 1

Hi Michael G

Are you sure your length is (3x - 5) and not 5x -2?

For the Rectangle

Area = length * width

Area/lendgth = width

If your area is

40x² - 6x - 4

If your length is

3x - 5

You can do the long division or you can factor the quadratic appropriately since you already have one of the factors.You can also use the Quadratic Formula The quadratic you have listed does not appear to have 3x - 5 as a factor.
