Answer 2

hold on a sec.

Answer 3

To add vectors, just add each part. So adding M and N...
<-2 + 1, 3 + 5, 6 + -2>

And once you get that, take each part and write it out using i, j, and k

For example, vector <1,2,3> in unit vectors is 1i + 2j + 3k

Answer 4

Yes i did that and got -1i 8j 3k but it does not match any of my answer choices

Answer 5

\(\large 6-2\neq 3\)

Answer 6

i have for on my paper but typed 3 my bad

Answer 7

wait, oops. sorry, do this instead...
<1- -2, 5-3, -2 - 6>

Answer 8

ok i got 3, 2 , -8 , and i see that as an answer THANK YOU!!

Answer 9

So when it says sum i subtract because its vectors?

Answer 10

You're welcome.

And yes. That rule I always mess up

Answer 11

sorry 'bout that

Answer 12

okay and then i am suppose to subtract them backwards N from M?

Answer 13

yeah.

Answer 14

OK thanks You :)

Answer 15
