(6)? If r(x) = 3x - 1 and s(x) = 2x + 1, which expression is equivalent to 3(6)-1 2(6)+1 (6) 2(6)+1 36-1 26+1 (6)-1 (6) + 1 Mark this and retum​

according to egenuity the answer is

step-by-step explanation:

d. 344.22

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°
