A
Step-by-step explanation:
Using PEMDAS you start with multiplication first, so -2 multiplied by -6, which is positive 12. Then you go from left to right, so 4 +-3, or 4-3, which is 1. Then 1-12 is -11. So your final answer is A, -11.
Using linear pairs,
By the exterior angle theorem,
Answer:
4. 
or -5 (It's a negative slope)
5. 0 (It's a horizontal line)
6. 
Formula: 
Your answer is going to be
(×+4) times (×+3)
Hope that helps you.
