Answer:

1)c 2)b 3)c 4)a

Step-by-step explanation:

1)x+5+11x-5

12x

2)5+11-6

10

3)4x+2-6x

-2x+2

4)12-3-4

5

Answer:

1:C 2:B 3:C 4:A

Step-by-step explanation:

1.)  x + 11x = 12x

    5 - 5

12x

____________

2.) f(5) = 5 + 11

    g(-2) = 3(-2)

    16 - 6 = 10

___________

3.) 4x - 6x + 2 = -2x + 2

_________________

4.) f(4) = 3(4) - 3

    12 - 3 =9

    g(2) = 2(2) = 4

9 - 4 = 5
