Part 1 out of 3 Based on these designs, is there more than one value for x? Complete the explanation for how you know this. ; because the perimeters are equal you get the equation (2x − 2) + (x + 1) + x + (x + 1) = (2x − 9) + (x + 1) + (x + 8) + x, Which simplifies to the statement 5x = , meaning that there for x.
