What is KN+IK? G H I J K L M N O

First, find the length of each segment.
To find the length of each segment, substract the value of the first letter from the value of the second one.
Since K=0 and N=3, then:
[tex]KN=3-0=3[/tex]Since I=-2 and K=0, then:
[tex]IK=0-(-2)=0+2=2[/tex]Then:
[tex]KN+IK=3+2=5[/tex]
