Planes a and b intersect in line s. if point v is a point on line s, then it lies on: plane a only plane b only both plane a and b neither plane a or b

  both plane A and B

Step-by-step explanation:

All the points on the line of intersection lie in both planes. V lies in both plane A and plane B.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
