In a triangle, the second side is 4 more than the first side. The third side is three times the first side. The perimeter is 9 meters. ¿what is the lenght of each side?
Subtracting 3 from either side results in.. 4x+3-3 = 47-3 4x= 44 Dividing both sides by 4 x=11 So second side of a triangle = x+3 = 11+3 Ans : 14 meter
