Answer: magnitude ab = 9.06
Step-by-step explanation:
The vector coordinates will be represented with ( X , Y )
Magnitude of ab will be
ab^2 = (X2 -X1)^2 + (Y2 -Y1)^2
ab^2 = (2 -1)^2 + (-3 -6)^2
ab^2 = 1^2 + 9^2
ab^2 = 1 + 81
ab = 9.06
Ok so you do 3x7= 21 which you already know. So then you do 1x7=7. Last, you just add 21+7=28 pens in total
