For this case we have the following vectors:
u = (1, -1, 3)
v = (-4, 5, 3)
We want to calculate the following operation:
3u - 2v
We have then:
3u - 2v = 3(1, -1, 3) - 2(-4, 5, 3)
Rewriting we have:
3u - 2v = (3, -3, 9) + (8, -10, -6)
3u - 2v = ((3 + 8), (-3 - 10), (9-6))
3u - 2v = (11, -13, 3)
Answer:
3u - 2v = (11, -13, 3)
option B
