The perimeter of a square is represented by the expression 4(4z − 6). Which statement is true?

• The perimeter can also be represented by the expression 8z − 2 because 4(4z − 6) can be simplified to 8z − 2.

• The perimeter can also be represented by the expression 8z − 6 because 4(4z − 6) can be simplified to 8z − 6.

• The perimeter can also be represented by the expression 16z − 6 because 4(4z − 6) can be simplified to 16z − 6.
