Evaluate the expression when a= 7 and b= 6.
4a + b

34

Step-by-step explanation:

4(7) + 6

(4×7) + 6

28 + 6 = 34

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°
