Which statement best explains the relationship between the variables?
Higher tuition causes students to graduate at higher
rates.
Tuition does not appear to have an association with
graduation rate.
More selective colleges tend to have higher tuition
but lower graduation rates.

and higher graduation rates.

a² + b²= c²

24² + 7² = c²

c= 25

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
