An equilateral triangle has a perimeter of 6x + 15.
a). write an expression to represent the length of each side of the triangle.
b). find the length of each side of the triangle if x=2 cm. show your work.
c). find the perimeter of the triangle.
d). justify, in word, how you found your answer.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

idk bring the function back   im not smart
