It usually helps a person to get a better idea of how much or how big something is. I'm actually not sure why, but let's use an example. You got 38 out of 43 questions on a test. when you see 38/43 you don't really know how good that score is, but if you make it a percentage (Dividing the first number by the second to get the percentage) it's 88%. You know you did well on that test.
13.6x[(3.4)+6.6]-2^2 —>13.6x10-2^2 —> 13.6x10-4 —> 136-4= 132
Answer: C, It stays the same.

Vectors in the same direction are called collinear.
Length ( u ) = 3 m
Length ( v ) = 5 m
Length ( u + v ) = Length ( u ) + Length ( v ) = 3 m + 5 m = 8 m
Answer:
C ) 8 m
