Answer: In other words, the answer is

(x+8) (x-8) (or) x^2 - 64

Here a = x and b = 8, thus if x + 8 is a factor, then x - 8 is also a factor.. (x + 8)(x- 8) <-- expand this out using difference of squares rules.

An item is regularly priced at $39. Ashley bought it at a discount of 55% off the regular price.

enot [183]

55% off the regular price means she paid 45% of the regular price. ( 100% - 55% = 45%

Multiply the original price by 45%:

39 x 0.45 = 17.55

She paid $17.55

(If you need to know how much she saved: 39 - 17.55 = $21.45)

The right rectangular prism is made up of 48 cubes. Each cube has an edge length of inch. What is the volume of this prism?

Gnesinka [82]

Given:

The right rectangular prism is made up of 48 cubes.
Each cube has an edge length of 1/4 inch.

$~$

To Find:

What is the volume of this prism?

$~$

Solution:

$~$

Using formula: 

$~$

$\sf \pmb {Volume \: of \: cube = {(side)}^{3} }$

$~$

Substituting values in the formula:

$~$

$\sf \longrightarrow \dfrac{1}{4} \times \dfrac{1}{4} \times \dfrac{1}{4}$

$\sf \longrightarrow \dfrac{1}{64} \: {inch}^{3}$

$~$

Now,

Volume of 48 such cubes = Volume of 1 cube × 48 cubes

$~$

$\sf \longrightarrow \dfrac{1}{64} \times 48$

$\sf \longrightarrow \dfrac{48}{64}$

$\sf \longrightarrow \dfrac{3}{4} \: {inch}^{3}$

$~$

Hence,

Volume of prism is 3/4 inch^3
