(−2)(a−b)+3(a+b) need help plzzz

a +5b

Step-by-step explanation:

(−2)(a−b)+3(a+b)

Distribute

-2a -2(-b) +3a +3b

-2a +2b +3a+3b

Combine like terms

-2a +3a   +2b +3b

a +5b

a + 5b

Step-by-step explanation:

(−2)(a−b)+3(a+b)

-2a + 2b + 3a + 3b

a + 5b

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°
