Answer:
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,
Length × width = area
Substituting the values we get,
(x - 4)(x) = 5x² - 18x - 8
x² - 4x = 5x² - 18x - 8
x² - 5x² - 4x + 18x = -8
-4x² + 14x = -8
-4x² + 14x + 8 = 0
Hence, This is the required expression which represent the width of the rectangle.
