B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

Here a = 1 and b = 3

f(b) = f(3) = 27 ← value of y corresponding to x = 3

f(a) = f(1) = 3 ← value of y corresponding to x = 1, thus

average rate of change = = = 12 → B

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest
