In the class work, The Why Of It? you saw three ways of thinking about why 2(X+1) is equivalent to 2X+2. Now use those ideas to explain your work in Question 1.

a. Use Caroline's repeated addition method to explain why your answer to Question 1a is equivalent to 3(P+4).
b. Use Nickie's numerical example method to explain why your answer to Question 1b is equivalent to 6(z−7).
c. Use Johan's area model method to explain why your answer to Question 1c is equivalent to 12(y+3).
