Question

A rectangle has an area of 8x2 - 2x - 45. The length of the

Answer 1

Answer:

$Width = W = 2x-5$

Step-by-step explanation:

Given Data:

Length of rectangle = L = $4x + 9$ ------->(Equation 1)

Area of rectangle = A = $8x^{2} - 2x -45$ square inches ------->(Equation 2)

To find out:  

Width of rectangle = W = ?  

Formula:  

Area = A = L×W

$Width = W = \frac{A}{L}$

Solution:  

$Width = W = \frac{A}{L}$

$Width = W = \frac{8x^{2} - 2x - 45 }{4x+9}$
