How do you find the perimeter of a figure?
Absolute Value Inequality: |2*3 + 2(x+1)-4x|≤3
Solution: 5/2 ≤ x ≤ 11/2
Let P_R be the perimeter of the rectangle and P_S be the perimeter of the square. We are told that the difference between the perimeters of the figures is less than or equal to 3. We can write this as an absolute value equation. |P_R-P_S| ≤ 3 We will now find the perimeter of each figure.
