What is the positive solution to the equation 0 = -x2 + 2x + 1?
Quadratic formula: x = -btvb2 - 4ac
20
o-2+2
02-√2
0 1+12
-1 + V2

1 : 2

Step-by-step explanation:

First situation

sides of triangle:-

a=x, b=2x, c=3x

then perimeter = a+b+c

perimeter = x + 2x + 3x

Perimeter = 6x

Second situation(sides are doubled)

sides of triangle:-

a=2x, b=4x, c=6x

then perimeter = a+b+c

perimeter = 2x + 4x + 6x

Perimeter = 12x

Ratio of first situation to second

Perimeter of first situation : Perimeter of second situation

6x : 12x

1 : 2
