15 since you know that pq is 6, and the graphs are symmetrical, so q(3,9) if you put 3 in the function y=x*x. then put q(3,9) into y=a-x^2, you’ll get a is 18
11, the third side should be as least as possible, thus it should be 30, then the perimeter is 30+30+50=110
7, you know thatx is 9, right?? then if y^z=16, z is bigger than y, think:16=2^4=4^2=16^1, so y is 2, and z is 4, xplus z is 13, choose D
