A 4 sided polygon is a quadrilateral
1. If x -3 is less than or equal to 12 ,then you will transpose 3 to the right and subtract 3 from 12
B. Add -12x to both sides. Then divide all terms by -2. The positive 12 on the right side will be a -6 and the -42 will be a positive 21. The inequality sign is always switched whenever the equation is divided by a negative number.
