Answer:
C. 850,668
Step-by-step explanation:
Since order doesn't matter, we use the combination equation: nCr
We first need to find n, which would be 42. Then we find r, which is 5.
We plug them into either the equation or a calculator
(42!)/(5!(42-5)!) = 850,668
6
2x -4 = 8 , 8+4=12 , 12÷2=6
it's 13a+2 pal!
