Step-by-step explanation:

The answer is B

B. x² + 2

Step-by-step explanation:

distribute the negative in the second part: 2x² + 2x + 3 - x² - 2x - 1

add like terms: 2x² - x² + 2x - 2x + 3 - 1

= x² + 2

2x - 2x cancels out

the answer is a i belaeve atleast thats what my calculator just gfave me

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°
