Zak is 6 years older than half his sister bellas age bella is 6 years old

Zak's is 9 year old

Step-by-step explanation:

Let the age of Zak be x and his sister's age be y

Given ; zak is 6 years older than half his sister bellas age

i.e , x = 6 + y/2 ... so this is the equation in which we put the value of Bella's age to get the age of Zak !

So, when Bella is 6 years old

i.e, y = 6

x = 6 + 6/2

x = 6 + 3

x = 9

So, Zak is ( x ) 9 year old !

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.

just keep asking questions until you have a better understanding.
