a man is five times as old as his son. if the the sum of their ages is 72, find the difference between their ages 

Step-by-step explanation:

Let the age of the son be x

age of man = 5x

sum of their ages = 72

so it becomes, x + 5x = 72

6x = 72

x = 72/6

x = 12

so son's age = 12 years

and man's age = 5x = 5 × 12 = 60

therefore, difference between their ages = 60 - 12 = 48

Hope this helps

step-by-step explanation:

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.
