Plz, Help me with this question.

Answer  10x - 15

Step-by-step explanation:

Because when you do the distributive property, you multiply the things in the parenthesis so 5 multiplied by 2x would be 10x and 5 multiplied by -3 would be -15. Hope this helps :)

i dont know

step-by-step explanation:

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°
