Use the formula
n(n-1)/2
which is the total number of connections between n points
So,
4(3)/2 = 6
the answer is option C.
Hope this helps
It can't be factored because there are no 2 numbers that when you multiply you get 35 and when you add you get 13.
To solve this you have to add 98 and 82 together then divide by three so the answer would be 60
No they cross each other like a highway. You are on the underpass and your friend passes over you. As in, they are crossing a bridge & you are below them.
