the perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the short side. Which equation can be used to find the side lengths if the longest side measures 6.2 cm?​

Step-by-step explanation:

If longest is x then shortest is x/2 and other side is 14.5-1.5x

6.2÷2=3.1 which is shortest side. 3.1+6.2=9.3, 14.5-9.3 is 5.2
