Answer:
8r + 9p
Step-by-step explanation:
Combine like terms. Like terms are terms with the same variables as well as the same amount of said variable.
In this case, combine 12p with -3p
8r + 12p - 3p
8r + (12p - 3p)
8r + 9p
8r + 9p is your answer.

Answer:
65
Step-by-step explanation:
Since these 115 and the angle adjacent to x are alternate interior angles, then that angle is equal to 115. That angle and x add up to 180, so we do 180-115, which is equal to 65.
Answer:multiply by three
Step-by-step explanation:
Answer:
See Below.
Step-by-step explanation:
Please refer to the diagram below.
We are given that O is the center of the circle, and chords MN and RS are intersected a P. OP is the bisector of ∠MPR. And we want to prove that MN = RS.
We will construct segments OK and OJ such that it perpendicularly bisects MN and RS.
Since OP bisects ∠MPR, it follows that:

And since OK and OJ are perpendicular bisectors:

Therefore:

By the Reflexive Property:

Therefore:

By AAS Congruence.
Hence:

By CPCTC.
Recall that congruent chords are equidistant from the center.
Thus, by converse, chords that are equidistant from the center are congruent.
Therefore:
