if y=x^2
all you have to do is plug in the numbers like for y it would be
4=x^2 it would be -2 and 2
The letter x has two lines of symmetry.
A is located, as you look A is past -2 almost hitting -3 making the mark 2.8 so the answer is A
I think it's 182 I'm not completely sure though
Since all of the side lengths are different, it is a scalene triangle
