The length of a rectangle is 3 inches greater than the width. write a polynomial that represents the area of the rectangle

Length of a rectangle is 3 inches greater than the width, so:

L = W + 3

Area of a rectangle:

A = L x W

A = ( W + 3 ) x W

A = W2 + 3 W Polynomial representing area of the rectangle in terms of Width.

Substitute W = 4 to find the area of the rectangle.

A = 42 + 3 (4)

A = 16 + 12

A = 28 inch2

L = W + 3

L = 4 + 3

L = 7 inches

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
