The document discusses the distributive property and how it is used to simplify algebraic expressions. It provides examples of distributing terms over addition and subtraction, such as 5(x + 7) = 5x + 35. It also discusses like terms and how they can be combined when simplifying expressions.

3. Example #2 3(m - 4) 3 • m - 3 • 4 3m - 12 Example #3 -2(y + 3) -2 • y + (-2) • 3 -2y + (-6) -2y - 6

7. Like Terms are terms with the same variable AND exponent. To simplify expressions with like terms, simply combine the like terms.

8. Are these like terms? 1) 13k, 22k Yes, the variables are the same . 2) 5ab, 4ba Yes, the order of the variables doesn’t matter. 3) x 3 y, xy 3 No, the exponents are on different variables.

10. The above expression simplifies to: 5a and a are like terms and are like terms

15. Which figure below models the simplification of - 4x - 5 + 7x + 7 using these tiles? Answer Now
