Best ResponseYou've already chosen the best response.0An expression is shown below: 3(m + 5 + 9m) Part A: Write two expressions that are equivalent to the given expression. Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m.

Best ResponseYou've already chosen the best response.1For the first part, distribute the 3. That gives you one equivalent expression.

Best ResponseYou've already chosen the best response.1To get a second equivalent expression, add m+9m. That gives you a second equivalent expression.

Best ResponseYou've already chosen the best response.13(m+5+9m)=3m+15+27m You don't have to combine the like terms according to the directions.

Best ResponseYou've already chosen the best response.1For the second part, explain that you used the distributive property like this: 3(m+5+9m)=3(m)+3(5)+3(9m)

Best ResponseYou've already chosen the best response.1For the third part pick a number like 2 and use the original expression and your other expression from part 2 and replace m with 2 in both expressions and show that you get the same answer for both.

Best ResponseYou've already chosen the best response.0@Mertsj so my two equivalent expressions are 15+30m and 3m+15+27m

Best ResponseYou've already chosen the best response.1When you distribute the 3 you get 3m+15+27m That's one of the equivalent expressions.

Best ResponseYou've already chosen the best response.1When you add m +9m you get 3(5+10m) That's the other equivalent expression
