Question

The area of a rectangle is (X - 5x² + 3x - 15), and the width of the rectangle is (x2 + 3). If area = length x width, what is the
length of the rectangle?
x + 5
x - 15
x + 15
x-5

Answer 1

Answer:

Step-by-step explanation:

Area of rectangle = x³-5x²+3x-15

Width of rectangle = x²+3

Length of rectangle= ?

We will apply the formula:

Area= length* width

Hence we know the area and width.

x³-5x²+3x-15/x²+3 = length

By dividing the terms we get (x-5).

Thus the correct option is x-5....
