Explain it ,and become brainlist​

Answer 1

Answer:

6,9&12

Step-by-step explanation:

let side be X,

then,sides are X,2x,2x-3

perimeter=27

=>x+2x+2x-3=27

=x=6

therefore 2x=12

2x-3=9.

Answer 2

Step-by-step explanation:

Let the shortest side be x.

then, the longest side would be 2x.

and the 3rd side would be 2x-3.

According to the question,

2x+x+(2x-3) =27

3x+2x-3=27

5x-3=27

5x=27+3

5x=30

x=30÷5

=6

Therefore, longest side=2x=2*6= 12

shortest side=x= 6

3rd side=2x-3=2(6) -3=12-3= 9
