The expression 12c-18 represents the perimeter of a regular hexagon. write two different expressions to describe its perimeter. then write an expression for the length of one of its sides.

If 12c-18 is the perimeter of a regular hexagon we can divide this by 6 to get the length of one side. (12c-18)/6 = 2c-3 as an expression for one side of the hexagon.

We need an expression that is equal to 12c-18 one possible expression is just 2c-3+2c-3+2c-3+2c-3+2c-3+2c-3 would be equal to 12c-18. The other expression would also have to equal 12c-18 we can divide this expression by to then add that quotient to itself. (12c-18)/2= 6c-9. 6c-9+6c-9

a.2c-3+2c-3+2c-3+2c-3+2c-3+2c-3

b.6c-9+6c-9

c. 2c-3
