-2 ( X + 3 ) =

Show work please or explanations

-2x-6

explanation: use the distributive property

>> -2(x) = -2x

-2(3) = -6

-2+-6 = -2-6

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°
