Forgive me if I've read your question wrong but I see
\frac{20-45x^2}{6x^2-x-2}
= \frac{5(4-9x^2)}{6x^2-x-2} =  \frac{5(2-3x)(2+3x)}{6x^2-x-2}
= \frac{5(2-3x)(2+3x)}{(3x+2)(3x-1)} =  \frac{5(2-3x)}{3x-1}

Mary has 50 earring boxes the boxes measure 1 inch on each side. How many rectangular prisms all with a different size base coul
Sholpan [36]
Given:
50 earring boxes with a measure of 1 inch each side

volume of boxes = a³ = 1³ = 1 in³
total volume of boxes = 1 in³ * 50 boxes = 50 in³

volume of a rectangular prism = length * width * height
50 in³ = length * width * height

Let us assume that the height is 1 in.

length and width can be factored:
50 x 1
25 x 2
10 x 5

<span>I can only make 3 rectangular prisms</span>

What is the solution of |x- 5|-2=10?
Lelu [443]

Answer:

x=17, x=-7

Step-by-step explanation:

Step  1  :

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |x-5|-2 = 10  

Another term is moved / added to the right hand side.

     |x-5| = 12  

Step  2  :

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |x-5|

For the Negative case we'll use -(x-5)  

For the Positive case we'll use (x-5)  

Step  3  :

Solve the Negative Case

     -(x-5) = 12  

    Multiply

     -x+5 = 12  

    Rearrange and Add up

     -x = 7  

    Multiply both sides by (-1)

     x = -7  

    Which is the solution for the Negative Case

Step  4  :

Solve the Positive Case

     (x-5) = 12  

    Rearrange and Add up

     x = 17  

    Which is the solution for the Positive Case

Step  5  :

Wrap up the solution

x=-7

x=17
