What is the value of 3n2 – 4m + 6 when n=4 and m= 18?
O 132
0 36
-3
0 -4

By substituting the values of m and n into the expression, 3(4)2 - 4(18) +6= -42

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
