When 4a - a x 3a + 7a is simplified it is equivalent to?

-3a^2 + 11a

Step-by-step explanation:

4a - (a x 3a) + 7a - Multiply first to get 4a - 3a^2 + 7a

4a - 3a^2 + 7a - Add like terms (a terms) to get -3a^2 + 11a

So the answer in -3a^2 + 11a

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°
