Please can someone help with this? I've been having a lot of problems with this. And if you could explain it an not just give me the answer, I'm trying to actually learn how to do this. Thank you for any help you can provide.

v ⋅ w

Given the vectors:

r = <8, 8, -6>; v = <3, -8, -3>; w = <-4, -2, -6>
