Answer:
24x^2+112x+120
Step-by-step explanation:
distribute the 2 
(6x+10)(4x+12)
foil it
24x^2+112x+120
 
        
             
        
        
        
5 seconds 
because that is the positive zero of that equation
        
                    
             
        
        
        
If you graph the two equations then you will find that they intersect at (-2,-2).
You then have to check your answer.
x=4y+6
(-2)=4(-2)+6
-2=-8+6
-2=-2
x-3y=4
(-2)-3(-2)=4
-2+6=4
4=4
        
             
        
        
        
multiply width times the height to get the rectangle area
5 x 7 = 35 units squared
I may be wrong but I think you may be over complicating it its okay I do that a lot too
