Answer 2

At first I got 18, then I got 0 so idk if it's right

Answer 3

It seems right to me!

Answer 4

0?

Answer 5

Yes.
As long as you're not dividing by 0 or doing something else weird, you can just plug in the number.

Answer 6

That's what I did but I'm not sure if I put -3 or 3 as the number. I'm confused about that lol

Answer 7

It doesn't even matter. Squared you get 9, which turns into \(\sqrt{0}\) and that makes the whole thing 0.

Answer 8

Oh okay thank you!!
