One side of a triangle is twice the smallest side. The third side is six feet more than the shortest side. The perimeter is 18 feet. Find the lengths of all three sides (in feet). (Enter your answers as a comma- separated list.) ft​

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
