im not sure but i thinkk its like this

Step-by-step explanation:

You use the distributive property so

4. 16

5. 18

in numbre six you multuply 6x5 and 5x5 then you add it and its 55

6.55

7.6

8.39

9.17

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°

just keep asking questions until you have a better understanding.
