The longest side of a triangle is 5 in. Longer than the shortest side. The medium side is 4 in. Longer than the shortest side. If the perimeter of the triangle is 30 in. What are the lengths of the sides ?

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

b. 2 and 4
