Answer:

(x+8)(x^2-3)

Step-by-step explanation:

First you need to factor out the greatest common factor from each group.

x^2(x+8) - 3(x+8)

Factor the polynomial by factoring out the greatest common factor, x+8.

( x + 8 ) ( x ^2-3 )

Danielle construct a scale model of a building with a rectangular base her model is 2 inches in length and 1 inch in width the s

Kitty [74]

Given:

a.) The scale of the model is 1 in equals 47 ft.

b.) Danielle constructs a scale model of a building with a rectangular base her model is 2 inches in length and 1 inch in width.

To be able to determine the actual area of the base, let's first identify the actual dimensions of the base.

We get,

$\text{Length: 2 (inches) x }\frac{47\text{ ft.}}{1\text{ (inch)}}\text{ = 2 x }\frac{47\text{ ft.}}{1}\text{ = 94 ft.}$ $\text{Width: 1 (inch) x }\frac{47\text{ ft.}}{1\text{ (inch)}}\text{ = 1 x }\frac{47\text{ ft.}}{1}\text{ = 47 ft.}$

Let's now solve for the area of the base, since it is a rectangle, we will be using the formula below:

$\text{ Area = L x W ; where L = Length and W = Width}$

We get,

$\text{ Area = L x W}$ $\text{ = 94 ft. x 47 ft.}$ $\text{ Area = 4,418 ft.}^2$

Therefore, the actual area of the base is 4,418 ft.².
