How do you factor 2x^4 - 2y^4

Mathematics

First factor out 2 

2(x^4 - y^4) 

Rewrite it as ((x^2)^2) and ((y^2)^2) 

Then you get..

2 ((x^2)^2) - (y^2)^2)) 

Now both terms are perfect squares, factor using the difference of squares formula, a^2 + b^2 = (a+b)(a-b) 

a= x^2 and b= y^2 

2((x^2 + y^2)(x+y)(x-y))

clean it up!

2(x^2 + y^2)(x+y)(x-y)

Abner wants to create a shopping budget where he spends less than $80 per month on clothes. He also wants to spend at least thre
strojnjashka [21]

Answer:

D) Abner can spend $60 per month on school clothes and $20 per month on gym clothes and stay within his budget.

Step-by-step explanation:

In the problem it states that Abner will spend 3 times more on (s)school clothes than (g) gym clothes.

So it would appear as s ≥ 3g.

If we plug in $60 as s (school clothes) and $20 as g (gym clothes), the statement is true.

60 ≥ 3(20)

60 ≥ 60. These numbers make the linear system true.

If you have trouble with this, an easy way to find this answer is simply creating the linear system that represents the problem, (he will buy 3 times more school clothes than gym clothes) s ≥  3g and plug in each variable from the answer choices until you find the variables that make the linear system true.

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.
ipn [44]

The difference of the fraction is \mathbf{  -\dfrac{3}{4}} by using equivalent expressions.

<h3>What is a number line?</h3>

A number line is a diagrammatic representation of real numbers on the graduated line. It ranges from negative axis to positive axis with 0 being the center position.

A sketch showing the representation of the difference in the mixed fractions can be seen in the image attached below.

Using equivalent expressions to determine the difference between the mixed fractions, we have;

\mathbf{ = -2\frac{1}{2} - (-1\dfrac{3}{4}) }

\mathbf{ = -2\frac{1}{2} +1\dfrac{3}{4} }

\mathbf{ = -\dfrac{5}{2} +\dfrac{7}{4} }

\mathbf{ = -\dfrac{3}{4}}
