36x^2-49
this closely matches the binomial formula of (a+b)*(a-b)=a^2-b^2
so we know:
a^2=36x^2
a=6x
b^2=49
b=7
so (a+b)*(a-b)=(6x+7)*(6x-7)=36x^2-49

Answer:
B. -3 ≤ y ≤ 9
Step-by-step explanation:
The range is the vertical extent of the graph. This graph extends from a minimum of y=-3 to a maximum of y=9. Then the range is ...
-3 ≤ y 9 . . . . matches choice B
I believe since it's a supplementary line, your answer will be 180-57
This would make your angle 123°. My apologies if I am wrong. I have not taken Geometry in a Year or two.
