Question

Find the distance between two parallel lines: x = 11 and x = 5.

Answer 1

`The\ distance:\\\\d=|11-5|=|6|=6`

Answer 2

`x = 11 ,\ \ \ A(11,0) \\ \\ x = 5 , \ \ \ B(5,0) \\ \\ distance \ between \ two \ parallel \ lines \ : \\ \\ d=\sqrt{(x_(2)-x_(1))^2 + (y_(2)-y_(1))^2}\\ \\d=√((5-11)^2+(0-0)^2)=√((-6)^2)=√(36)=6`
