Write an expression for the perimeter in simplest form. *look at the picture*

A) 2x2 - 24x
B) 4x + 24
C) 4x - 24
D) x2 - 12x

answer:

c) the x-coordinate of the center of the circle increases by 3

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
