One less than five times a number is fewer than twenty-four.

one Less than 5 is 4 times 5 equals 20

Step-by-step explanation: 5 minus 1 is 4 times 5 equals 20

it would be 6xy and -16xy.

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.
