"if a=2, what is the simplified form of the expression below? (x)(x^2+ax+a^2)"

a=2

expression --->  (x)(x^2+ax+a^2)

               when a =2,  (x)(x^2+2x+2^2)      

                NOW DISTRIBUTE THE x

                      x^3+2x^2+4

hope it helps u mate!!!

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°
