Given vectors u= (1,1,3) and v= (4,5,3) find an ordered triple that represents vectors 3u2v.
a.(16,1,7)
b.(11,13,3)
c.(10,12,1)
d.(7,7,16)
I don't want you to straight up give me the answer. I need someone to teach me how to solve this problem. I am home schooled and i cant figure this out.

3 u = +3i  3 j + 9k
2 v = 8i + 10j + 6k
 subtract
1 x = 11i  13j + 3k
so I think b
