can someone help me?!!!!!

Answer:
7 units, north
Explanation:
This is a problem of vector subtraction. We have:
- Vector A: magnitude 2 units, direction to the north
- Vector B: magnitude 5 units, direction to the south
If we take the north as positive direction, we can write
[tex]A = +2\\B=-5[/tex]
Since we want to find [tex]A-B[/tex] (vector subtraction), we have to change the sign of B, so we find:
[tex]A-B=+2-(-5))=+2+5=+7[/tex]
And the positive sign means the direction is north.
