Will give 1.find the length of line segment ab when a=(2, 0) and b=(2, 6) 2.find the length of cd: c(12, -10) and d(0, -6) 3.find the length of ef: e(-3, 2) and f(6, 2)

To find the distance you can use the formula

Just a second zzz

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
