12. Entry 24 – Problem 2-26 In problem 2-25, you represented algebraic expressions with algebra tiles. In this problem, you will need to reverse your thinking to write an expression from a diagram of algebra tiles. Working with your partner, write algebraic expressions for each representation below. Start by building each problem using your algebra tiles. A. + --------------------- - B. + --------------------- - X X y
