Question

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 help

Answer 1

The answer is:
B; 3(4x + 6): Each side length is 4x + 6 units

Answer 2

4x+6

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
