A sequence of transformations maps ABC onto AB'C'. The type of transformation that maps ABC onto ABC is a___
When A”B”C” is reflected across the line x = -2 to form AB'C', vertex___
of AAB'C' will have the same coordinates as B.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
