Answer: p(-1) = -15
Step-by-step:
Plug -1 into the equation in place of q.
p(-1) = (-1)^2 + 4(-1) - 12
p(-1) = (-1)^2 - 4 - 12
p(-1) = (-1)^2 -16
p(-1) = 1 - 16
p(-1) = -15

Answer:
This triangle is not a right triangle
Step-by-step explanation:
If it were a right triangle, then the pythagorean theorum would work
a^2 + b^2 = c^2
12^2 + 7^2 = 15^2
144 + 49 = 225
This is not true because 144+49=193, not 225
So this triangle is not a right triangle
