Your answer should be a polynomial in standard form.

x^2+6x+8

Step-by-step explanation:

I got it wrong on khan academy and this ended up being the answer.

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°

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
