Which of the following is a factor of 7x^2 -12x-4?
a) x+2
b)none of the above
c)7x-2
d)x-4

After simplifying you will get (7x+2)(x-2)=0. This means that the answer is 

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
