A. Definition of linear pair
Step-by-step explanation:
A linear pair of angles is formed when two lines intersect. Since angle on a straight line = 180°, angles of a linear pair sum up to 180°.
angles 1 and 4, angles 2 and 5, angles 3 and 6 are all linear pairs. Each pair = 180°.

Answer:
See below.
Step-by-step explanation:
A good idea would be to write if as:
-x^4 + 0x^3 + 0x^2 + 0x + 1, then you can perform long division.
