Answer: 7.5"
Step-by-step explanation:
First, take away the extra 5" on the longer side lengths
40-5-5=30
Then divide by 4 to get the width
30/4=7.5
This works because if you took the 7.5" and added back the 5 inches, it makes 12.5. Then add all 4 sides together, you get 40.
7.5+7.5+12.5+12.5=
 
        
                    
             
        
        
        
Sorry i’m not gonna graph it but with this info u easily can
the y intercept is -1
slope is 3/1
final equation is y=3x-1
