<em>x</em> = 3.9 x -8.58
<em>x</em> = -33.462
 
        
                    
             
        
        
        
<span>The ratio of areas is the square of the ratio of perimeters;
The area of triangle B / The area of triangle A = 25 ;
The perimeter of triangle B / The perimeter of triangle A = </span>

The perimeter of triangle B is 5many times greater than the perimeter of<span>triangle A!</span>
 
        
        
        
Answer:
3x2+15x=18
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6
