Can someone do 11-16 with the work shown?

Ughhh. I'm only helping because I want points and I'm bored. Just please tell me if you actually need help or if you are lazy.

Questions 11/16 all involve simplifying like terms and using additional properties.

11) b - 2 + 6 - b
      -2 + 6
      4

12) -3k + 9k
       6k

13) -7(1 + 6v)
      -7 + (-42v)
      -7 - 42v

14) 4(x+7)
      4x + 28

15) 3(x-3) + 5x
      3x - 9 + 5x
      8x - 9

16) -4(n-3) + 6
      -4n + 12 + 6
      -4n + 18

Ithink b hope that

The sum of the angles in a triangle is 180°. this is called the angle-sum property.the sum of the lengths of any two sides of a triangle is greater than the length of the third side. similarly, the difference between the lengths of any two sides of a triangle is less than the length of the third side.the side opposite to the largest angle is the longest side of the triangle and the side opposite to the smallest angle is the shortest side of the triangle.
