I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2

Answer:
2 units
Step-by-step explanation:
Since a reflection doesn't change the angle or line segment measurements, Triangle A'B'C' will be congruent to Triangle ABC. Therefore, segment AB would be equivalent to segment A'B' and since segment AB=2 units, segment A'B' would equal 2 units as well.
