What is the expression as an exponent expression?
25•25•25•25•(-p)•(-p)•(-p)•(-p)•(-p )

25^4 x -p^5

^ as in the exponent

x as in times

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°
