Question

Ms. Alice wrote the expression below the board for the class. She asked the class to write an equivalent expression using no more that one sets of parentheses.
5(4x + 6y +4z) + 4(x - 2z)

Leah wrote 20 x + 30y +20 z
Michelle wrote 6(4x + 5y +2z)
Nicol wrote 8x + 6y + 2z

Answer 1

Answer:

Michelle

Step-by-step explanation:

if we open the paranthesis the equation expands:

20x + 30y + 20z + 4x - 8z  =  24x + 30y + 12z

that equals: 6(4x + 5y +2z)
