Find the value of c that makes the expression a perfect square trinomial. Then write the expression as the square of a binomial. x² + 8x + c

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.

you would need to also lose 1 point for each of the other outcomes for it to be fair.

y= -2x+4, have a great day
