Step-by-step explanation:
Given the schedule above :
Red line arrives every 4 minutes
Blue line arrives every 5 minutes

All three just arrives at the train station ; when next will they all arrive at the train station at the same time.
Obtain the lowest common multiple of each arrov time :
Lowest common multiple of 4, 5, 6
_2___4___5___6
_2___2___5___3
_3___1___ 5 __ 3

Ο Α) π

is my answer correct?
abs(x - 1) > 2
Result one
x - 1 > 2
x > 2 + 1
x > 3 but it does not include 3 so you were right about that.
x - 1 < - 2
x < -2 + 1
x < - 1
Looks like D to me.
Note these questions when they work will give you 2 answers. The second one is always a sign switch.
Again try 2 values. Try 0 and - 2 for x
