Answer:

Final answer is $(3x-y)(x+y)$ .

Step-by-step explanation:

Given expression is $3x^2+2xy-y^2$ .

Now we need to factor the given expression $3x^2+2xy-y^2$ completely. Let's use factor by grouping method.

$3x^2+2xy-y^2$

$=3x^2+3xy-xy-y^2$

$=3x(x+y)-y(x+y)$

$=(3x-y)(x+y)$

Hence final answer is $(3x-y)(x+y)$ .

(3x−y)(x+y) is the answer but did you mean to put 3x^2 + 2xy - y^2 as your answer?

Hi there!

To solve this problem, first we need to convert everything into feet.

1.5 mi = 7920 ft

Since
7920 is greater than 3520,

Ashley lives closer to the school.

Hope this helps!

Compare the fraction 3/5 to 1/2 and then compare 2/6 to 1/2. Use symbols in your answer

Hello there!

"Compare the fraction 3/5 to 1/2 and then compare 2/6 to 1/2. Use symbols in your answer"

To make this easier, we will make it so that both fractions in each pair has like bases.

To make 3/5 and 1/2 have a like base, we must make the denominators 10. To do this, we will do the following:

(3*2)/(5*2) = 6/10

(1*5)/(2*5) = 5/10

Now we can easily compare and not worry about the denominator

So, let's just look at the numerators.

Which is greater, 5 or 6? We know 6 is greater, so:

6/10 > 5/10

That means:

3/5 > 1/2

Now, we must do the same for 2/6 and 1/2

We will make them both 6. So, we can leave 2/6 alone

2/6

(1*3)/(2*3) = 3/6

Now we have 2/6 and 3/6

Which is greater, 3 or 2. The answer to that is 2. So:

3/6 > 2/6

This means that 1/2 > 2/6

Our answers are:

1. 3/6 > 2/6

2. 1/2 > 2/6

I hope I was able to help you!
