Answer:
Linear Pair:
∠ 1 and ∠ 2
Vertical Angles:
∠ 1 and ∠ 3
Supplementary Angles:
∠ 7 and ∠ 6 
Step-by-step explanation:
Linear Pair:
A linear pair of angles is formed when two lines intersect. 
Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. 
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Example
∠ 1 and ∠ 2           ∠ 8 and ∠ 5 ,etc
Vertical Angles:
The angles opposite each other when two lines cross. 
They are always equal.
Example
∠ 1 and ∠ 3           ∠ 8 and ∠ 6 ,etc
Supplementary Angles:
Two Angles are Supplementary when they add up to 180 degrees. 
Examples  two angles (140° and 40°)
All Linear pair are Supplementary angles
Example
∠ 7 and ∠ 6           ∠ 8 and ∠ 5 ,etc

Answer:5p^3-2p^2-7p+1
Step-by-step explanation:
-3p^3+5p+(-2p^2)+(-4)-12p+5-(-8p^3)
open brackets 
-3p^3+5p-2p^2-4-12p+5+8p^3
Collect like terms 
-3p^3+8p^3-2p^2+5p-12p-4+5
5p^3-2p^2-7p+1
