7 4/3 write the expression in radical form simplify if possible

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
