Let "a" be a vector of length 2, and let "b" and "c" be vectors such that \(\mathbf{a} \bullet \mathbf{b} = 3, \mathbf{a} \bullet \mathbf{c} = 4, \mathbf{b} \bullet \mathbf{c} = 5.\)
Enter in the numbers \(\mathbf{a}\bullet( \mathbf{b} + \mathbf{c}), \mathbf{b}\bullet(\mathbf{a} +\mathbf{b} + \mathbf{c}), (\mathbf{a} + 2\mathbf{b})\bullet(-3\mathbf{a} + 3\mathbf{c})\)

below, in the order listed above. If any of these cannot be uniquely determined from the information given, answer with a question mark.

 

I would really appreciate an explanation as well as an answer, thank you!

So if this is not answered 'soon'  you will no longer be interested in the answer?

So you do not want to understand you just want the answer?  ok, Got it.
