Answer:
D or 3
Step-by-step explanation:
The equation you are saying is
-x = x-6

I got this right on my assignment
Let's call the short side "s"
short side = "s"
middle side = 3s
longest side = 2*3*s
perimeter = 45 cm
perimeter = s + 3s + 6s = 45
short side = 4.5
middle = 13.5
long side = 27
4.5 + 13.5 + 27 = 45
