Given the number x=78 and y=-13 which statement is true

|x| = |78| = 78

so x = 78

and

|y| = |-13| =  13

so y = 13

Answer is C.  |x| = 78 and  |y| = 13

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.
