Please answer quickly i will give you brainliest if its correct- it has to be a simplified fraction please

Step-by-step explanation:

x and y are proportional.

Let x = 45 and y = 5.

Solve for r (constant of proportionality).

Divide both sides by 45.

Simplify and switch sides.

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.
