I believe #6 has rotational symmetry.

Step-by-step explanation:

It is rotated at an angle that could probably be rotated towards its original angle. As for #5, I don't think it has any.

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
