In ΔOPQ, \overline{OQ} OQ is extended through point Q to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\angle OPQ = (2x-3)^{\circ}m∠OPQ=(2x−3) ∘ , and \text{m}\angle QOP = (x+16)^{\circ}m∠QOP=(x+16) ∘ . Find \text{m}\angle PQR. m∠PQR.

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

you,

it is 10.6 according to my calculations

there were a lot of them but the first one to pop up on a google search was bts
