I believe the height is 9
x2 =9
x4 =64
64-9 =55
4-2 = 2
55/2 = 27.5
average rate is 27.5, B is the answer
11. 8/7
14. 13/10
17. 11/14
The prime factorization of any number means to get the factors of the number in simplest form.
99 = 3 x 33
We have 33 that needs to be factored.
33 = 3 x 11
We now have:
3 x 3 x 11
3^2 x 11 is your prime factorization (from the given answers).
I hope this helps!
