The axis of symmetry is -6 because the x always lies.
I could be wrong but i graphed it out and 9 is C , 10 is A , and 11 is C Hopefully it's right
√8+√18−√32
√2^2·2+√3^2·2−√2^4·2
√2^ 2·√2+√3^2·√2−√2^4·√2
√2 is the answer
The answer is none of the lines intersect each other, because they are at the same slope, and they do not have a different slope for the lines to be intersected.
