Answer:
0
Step-by-step explanation:
It increases by two for each interval
Given:
1. Combining like terms (here terms 6x and 2x both contain x, then we can combine them):

2. Distributive postulate:

The equation is

3. Zero product postulate (zero product postulate state that if a product of two factors is equal to zero, then first factor is equal to zero or second factor is equal to zero):

4. Subtraction property of equality:
a) subtract 6 from the first equation:

b) subtract 2 from the second equation:

Answer:
Terminal side in 2nd Quadrant
Only sin(x) & cosec(x) are positive in 2nd Quadrant

Perpendicular=5
Base=√(13²-5²)=√(169-25)=√144=√12²=12
Hypotenuse=13

7/-15 cuz 17-10=7 and (-7)-8=25
