Answer:
- shared short side: 10x +6
- shared long side: 8x +6
Step-by-step explanation:
The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...
4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common
If the long side (2x+1) was common, then the perimeter of the combined lot is ...
4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common
1-4 will equal -3 because if you look on a number line and move 4 to the LEFT of 1 it will take you to -3. I hope this helps you! and have a great day!
