Suppose that the relation t is defined as follows. t={(2,p) , (3,2) , (8, n) , (8,0)} give the domain and range of t . write your answers using set notation. domain - range - !

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

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.
