What do I do with the r values?
OpenStudy (anonymous):
\[
<1,2> - <5,2> = <1-5,2-2> = <-4,0>
\]
OpenStudy (anonymous):
Since r isn't in the expression, we don't need to worry about it.
OpenStudy (anonymous):
so the new values would be <-6,9,-7>??

OpenStudy (anonymous):
How do I change the format of my answer to match one of those?
OpenStudy (anonymous):
You don't.
The expression is wrong of the vectors are wrong.
OpenStudy (anonymous):
Then what am I supposed to do with an unlisted answer? This is quite the conundrum
