Ms. Peterson wrote the expression below on the chalkboard for her class. She asked the students to write an equivalent expressio
n using no more than one set of parentheses. 4(3x + 5y + 2z) + 3(x-z) Tom wrote 12x + 20y + 8z
Jenna wrote 5(3x + 4y + z)
Chris wrote 15x + 20y − 5z
Which, if any, of the three students wrote an expression that is equivalent to Ms. Peterson’s expression?
The answer would be Jenna's answer. If you distribute the teachers original expression you get 15x + 20y + 5. If you distribute Jenna's answer you get just that.
