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.

Answer 1

I'll just help quickly with a couple of expressions that are equivalent.
3(m+5+9m)
If you solve it out, you get 3m+15+27m.
Simply the expression to get 30m+15.
You can regroup to make another expression 5(6m+3) which is also equal.
