2x + 9 + 3x + x = 
6x + 9 =
when u use : 6x + 9 u will have infinite solutions
when u use 6x + 8 u will have no solutions
when u use 5x + 7 u will have 1 solution
        
             
        
        
        
1/4 of 1 minute would be 1/4 * 60(seconds in a minute)
so that would be 60/4=15 seconds.
 
        
                    
             
        
        
        
We will have to use the distance formula in order to determine the lengths of each side of the triangle.
Distance formula: 

Let's calculate AB first:
A (1, 7) and B (-2, 2)
A: x1 = 1 and y1 = 7
B: x2 = -2 and y2 = 2
so



AB = 

 or (rounded to the nearest tenth) ≈ 5.8
Now let's do BC:
B: x1 = -2 and y1 = 2
C: x2 = 4 and y2 = 2
So


BC = 

 or 6
Now let's do CA
C: x1 = 4 and y1 = 2
A: x2 = 1 and y2 = 7
So



CA = 

 or (rounded to the nearest tenth) ≈ 5.8
So let's recap:
AB ≈ 5.8
BC = 6
CA ≈ 5.8
So AB and AC are the same length while BC is .2 units longer which means this is an 
isosceles triangle.
 
        
        
        
Answer:
3x-24
Step-by-step explanation:
because 3x-24 divide both side by co efficient of x which is 3 so 24/3=8
