Answer:I think Jordan is this a trick question 
Step-by-step explanation:
 
        
                    
             
        
        
        
(2x+1)(x+1)
Now multiply 2x to both x and +1 
2x^2+2x 
Do the same with 1 multiply it to x and +1
2x^2+2x +x+1
Simplify 
2x^2+3x+1
        
                    
             
        
        
        
Maybe 400, but I’m not quite sure
