Caleb and sergio stacked boxes on a shelf. caleb lifted 14 boxes and sergio lifted 12 boxes. the boxes that sergio lifted each weighed 10 lb more than the boxes caleb lifted. which expression represents the total number of pounds sergio lifted? let c represent the weight of each box caleb lifted. a. 120c b. c + 10. c.12(c + 10) d. 10(c − 12)

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.
