Given vectors a and b, which operation does the green vector show? options: 2a + b a - b a + b ab

If we treat  b sliding vector, then head of green vector coincide with tail of b vector. So,in this Senior a is acting as a resultant vector. To get this resultant  vector a, the green vector must be a-b.

What class is this? i have no idea and i'm not going to give you the wrong answer. do you have a graph that goes with all the questions
