In a rhombus, all sides are equal:
5x = 15
and x = 15/5 = 3
(you could have done the same thing with the other side: 5x = 4x +3)
        
                    
             
        
        
        
Answer:
21 rootunder 15
Step-by-step explanation:
 
        
                    
             
        
        
        
(9,0) (0,9) choose any two points since it’s a straight line honey and the dk the difference between the two points 
9-0
———. = 1
0-9
        
             
        
        
        
The answer t our question is the first one
I just substituted he number one in every x 
The original equation is equal to 147 when x equals to 1
And the first option is also equal to 147 when x equals to one
