5x-7
If the first side is just x, then the second side must be 2x-5, or 5 less than twice the first. If this is the second side, then the third must be 2x-2, because the third side "measures 3 more than the second side."
The perimeter is 5x-7 = (x) + (2x-5) + (2x-2).
        
             
        
        
        
62 can go into 584 nine times which will be 558. 584-558=26. Bring down your 1 which will now be 261. 62 can go into 261 four times which will be 248. 261-242=13. So the top answer should be, 94 R 13.
