how many numbers in the above set are divisible by 11 but not by 22?

23 200

Step-by-step explanation:

/68,;67/$556::&&6-/7***://

9

Step-by-step explanation:

My reasoning is that there are 18 numbers divisible by eleven between 1 and 200 (multiples of 11). 22 has only 9 multiples between 1-200, and since only half overlap (share a multiple) only 9 remain (these include 11, 33, 55, ect)

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
