Answer:
Second option?
Step-by-step explanation:
I would go with the second one. It cannot be the first one because a function must have one y value per each x, but in this case it does not. Same reason for option 3 and 4. Am I right? Please let me know :)

Answer:
h(h(10))---> h(-4)---->10 ......hOh(10)=10
Step-by-step explanation:
X=4. First, you do 15/12 and get 1.25. You do this to see what number you have to multiply 12 to, to get 15. Since the sides a proportional it should be the same for the sides with their variables. Then you create an expression that puts the numbers the same place where 15 and 12 were to equal 1.25. You cross multiply, solve and get 4.
Well it really depends what u r solving for. So for perimeter u could add both X’s so 2x, and then add 10+2 which is 12. So it would be 2x+12. Not 100% right but I tried hope this helps and good luck!
