Convince Me! why are there two possible solutions is valid in this situation.

Answer
5.0/5
10

carlosego genius 11.6k answer 175.7m people helped the perimeter is the sum of the sides: P=(x-7) +(x+1)+(x) rewriting: P=3x-6 the area is giving by:A=(1/2)*(x-7)*(x) the area and the perimeter are the same: (1/2)*(x-7)*(x)=3x-6 rewriting: (x-7)*(x)=6x-12 x^2-7x-6x+12=0 x^2-13x+12=0 polynomial of degree 2, therefore there are 2 possible solutions. Viable solution. Viable solution: x=12 sides of triangle: 5 12 13

I think it’s like hope you get it right
