A square since all sides are equal and the angles aren't acute so it can't be a rhombus
        
                    
             
        
        
        
2(4x+5)>7x+20  perform indicated multiplication on left side
8x+10>7x+20  subtract 7x from both sides
x+10>20  subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
        
             
        
        
        
So here. I don't know how to explain so- 
 
        
                    
             
        
        
        
You were using it for 6 hours because 70-25 is 45 and if you divide 7.50 and hour and 45 it’s 6
