First, you have to multiply 60000 by 3 and you will get 180000. Then you add 4 and your final answer is 180004
        
             
        
        
        
Let x = width
x+1 is then the length
2x+2(x+1)=66
2x+2x+2=66
4x=64
x=16
deck will be 16x17, nice for a BBQ. :)

Hi there!
I believe the answer would be A. Addition Property of Equality 
Adding 0.36 to both sides of the equation and x being -5 means that the value is true, making it the A.
Hope this helps !
