Answer:
D-70
Step-by-step explanation:
It is a combination C(8,4)
I can help you. What is your question? Can you tell me?
So df = 8 so then 2x-6=8 which means that x is 7
If you substitute a variable for each blank, for example x*2+x*3 you get 5x=12, which can then be solved to get that x=12/5, so 12/5 is the answer.
