With expanded notation, how do u do this! ? number 15 and 16

15: 10,000 + 400 + 50 + 8

16: 100,000 + 80,000 + 70 + 5

note: hope i helped, have a great day :)

Step-by-step explanation:

36

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°
