Find the distance between l1 and l2:

l1: r=(6,-4,0)+t(0,-1,1); l2: r=(0,5,3)+s(-2,0,1)

Can someone just check or verify if my answer is correct?

PQ=(-6,9,3)

n=(-1,-2,-2)

|n|=3

D=(-6,9,3) . (-1,-2,-2)

3

final answer

Distance is 6 units.

Let me know and thanks for your help because there are no answers to these q's in the back.
