Answer:

  • -4x² + 14x + 8

Step-by-step Step-by-step explanation:

It's given that, The area of a rectangle in square inches is 5x² - 18x - 8 and the length of the rectangle is x - 4 inches.

Let the width of the rectangle be x inchez

We know that area of Rectangle is calculated by,


:\implies Length × width = area

Substituting the values we get,


:\implies (x - 4)(x) = 5x² - 18x - 8


:\implies x² - 4x = 5x² - 18x - 8


:\implies x² - 5x² - 4x + 18x = -8


:\implies -4x² + 14x = -8


:\implies -4x² + 14x + 8 = 0

Hence, This is the required expression which represent the width of the rectangle.
