Answer:
This is true
Step-by-step explanation:
You are division by 12/6 by 3 and that =4/2
The answer should be something like 12, 33, 56, 66, 77
For the given vectors
and 
The dot product of vectors a and b is defined as = 
So, 

= -16+12
= -4
10 1/2x +2
- because you would add all the side lengths, so 2x+2x+ 3 1/4x+ 13 1/4x 1. You can combine like terms it to 10 1/2x+ 2.
No because they are not following the same rule
