Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length),  (x+y) (width), and (x-y) (height)

Claudia says that she used the GCF to factor the expression 20x + 100xy as 20(x + 5xy). Is she correct? Explain.
Keith_Richards [23]

No, She is not correct.

Step-by-step explanation:

To find the greatest common factor of the expression 20x + 100xy.

Given expression 20x + 100xy.

Let us factor the expression 20x + 100xy.

Now take the common factor in the expression 20x + 100xy.

The common factor is 20x.

So, 20x + 100xy = 20x( 1+ 5y)

But Claudia says that the greatest common factor is 20(x+5xy).

The GCF is wrong.

So, she is not correct.

Please explain the problem to me step by step​
JulijaS [17]
<h3>Solution:</h3>

\frac{4y}{9}  -  \frac{2y}{3}  = 10 \\  =  >  \frac{4y - 6y}{9}  = 10 \\  =  >  \frac{ - 2y}{9}  = 10 \\  =  > y = 10 \times  \frac{9}{ - 2}  \\  =  > y =  - 5 \times 9 \\  =  > y =  - 45

<h3>Answer:</h3>
