Answer:

9999

Step-by-step explanation:

Given

(100 + 1)(100 - 1) ← these are the factors of a difference of squares.

a² - b² = (a + b)(a - b) , thus

(100 + 1)(100 - 1)

= 100² - 1

= 10000 - 1

= 9999

Savatey [412]

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:

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

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

For complete division check the attached image.

$Width = W = 2x-5$ inches
