Which algebraic expression means “three more than a number squared”?

Let "a number" = x

3 more = +3

number squared = x²

x² + 3 is your answer

hope this helps

i think the answer is seven, for if i'm being useless °ω°

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°
