A rectangle has an area of 8x2 - 2x - 45. The length of the
rectangle is 4x +9.
The formula for the area of a rectangle is: A=LxW
a. What is the width of the rectangle?
b. Explain how you solved the problem.

Respuesta :

Answer:

[tex]Width = W = 2x-5[/tex]

Step-by-step explanation:

Given Data:

Length of rectangle = L = [tex]4x + 9[/tex] ------->(Equation 1)

Area of rectangle = A = [tex]8x^{2} - 2x -45[/tex] square inches ------->(Equation 2)

To find out:  

Width of rectangle = W = ?  

Formula:  

Area = A = L×W

[tex]Width = W = \frac{A}{L}[/tex]

Solution:  

[tex]Width = W = \frac{A}{L}[/tex]

[tex]Width = W = \frac{8x^{2} - 2x - 45 }{4x+9}[/tex]

For complete division check the attached image.

[tex]Width = W = 2x-5[/tex] inches
