As Randi started to solve for in the diagram at right, she wrote the equation 72 + x = (x + 1).a. Is Randi's equation

As Randi started to solve for in the diagram at right, she wrote the equation 72 + x² = (x + 1)².a. Is Randi's equation valid? Explain your thinking.Hint (a):b. To solve her equation, first rewrite (x + 1)2 by multiplying (x + 1)(x + 1). You may want to review the Math Notes box for Lesson 2.2.2.c. Now solve your equation for x.Hint (c):d. What is the perimeter of Randi's triangle??Hint (d):Use the value of x to determine the length of each side of the triangle.
