Let $g$ denote the centroid of triangle $abc$. if triangle $abg$ is equilateral with side length 2, then determine the perimeter of triangle $abc$. 99 points! for right answer!

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.

answer: -2+√x,-2-√x
