An equilateral triangle has a perimeter of 12x + 18 units. which expression can be used to show the length of one side of the triangle?

plz

4x+6

Step-by-step explanation:

We are given that:

An equilateral triangle has a perimeter of 12x + 18 units.

We know that sides of an equilateral triangle are equal

Let each side be equal to x

Then, perimeter=sum of sides

                         = 3x

Hence, 3x=12x+18

             3x=3(4x+6)

i.e.    x=4x+6

Hence, expression that can be used to show the length of one side of triangle=   4x+6
