After Lin makes her way down the hallway, will locker number 56 have 0 magnets, 1 magnet, or both magnets?

0 magnets

Step-by-step explanation:

1 magnet because 56 is only a multiple of 7

so your answer would be C

step-by-step explanation:

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
