2x + 6 cm
5(x - 3) cm
Find the length of one side of the equilateral triangle.

side = 20 cm

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate the 2 given sides and solve for x

5(x - 3) = 2x + 6

5x - 15 = 2x + 6 ( subtract 2x from both sides )

3x - 15 = 6 ( add 15 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

then length of side is

2x + 6 = 2(7) + 6 = 14 + 6 = 20 cm

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

6 on both sides and twelve on the top and the bottom
