(<em>u</em> × <em>v</em>) • <em>w</em> makes sense, since <em>u</em> × <em>v</em> is another vector, and so (<em>u</em> × <em>v</em>) • <em>w</em> is a scalar.
<em>u</em> × (<em>v</em> • <em>w</em>) does not make sense, since <em>v</em> • <em>w</em> is a scalar, and the cross product is not defined between a vector and a scalar.

Answer:
25
Explanation:
In the first number 5 has a value of 500 and on the second one 5 has a value of 0.05 so 500 x 0.05 = 25
You have to divide 28 by two, then times the answer (14) by five, making it 70
Answer:
5 1/4
Step-by-step explanation:
cause if you multiply those numbers you should get the answer
