Answer:
x = -6 and x = 4
Step-by-step explanation:
In math, the critical points of a function are the points where the derivative equals zero.
So, first we will find the derivative of the function. The derivative is:

Now, we are going to make the derivative equal zero and find the answers of the equation.

So we have that the critical points are the answers to this equation:

and

Thus, the critical points are x=-6 and x=4

Answer:
86 degrees
Step-by-step explanation:
180 - (74 + 20) = 86
X = y + 11
2x + y = -2
2(y + 11) + y = -2
2y + 22 + y = -2
3y + 22 = -2
3y = -24
y = -8
x = y + 11
x = -8 + 11
x = 3
Solution set {3, -8} (C)
