Please answer all questions. I will give good review thanks.

Given two vectors u = 25': + Sr and v = 45'c + 237, determine the following: o u + v o u 3V 0 |2u + v| 0 Concept: Is u+v the same as u v ? 0 Concept: A scalar \"scales\" the length of a vector and component, and we know that it is multiplied to a vector to scale its length. However, can a scalar be added to a vector? why or why not? a Graphing: On a separate sheet of paper, draw the vectors u and v starting from the origin. Now draw the vectors using the \"head-totail\" method with v u as the result. a Show that v + u and u + v are the same geometrically by drawing both addition of vectors on a graph. What kind of geometric shape do we obtain
