48f^2-110f+63

Step-by-step explanation:

We multiple every part of first sum with every prt of the 2nd sum:

(6f-7)(8f-9)=48f^2-54f-56f+63=

48f^2-110f+63

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°
