When directed to completely factor the polynomial 4x2y5-8xy3, a student wrote 2xy3(2xy3-4). When the teacher did not give the student full credit, the student complained because when his answer is multiplied out, the result is the original polynomial. What went wrong?

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°

ƒ = 0.03b
