The statements that apply to the algebraic expression are
- Replace “a number” with the variable, n.
- The two operations are multiplication and subtraction.
- The constants are 2 and 6.
- The expression is written as 2(n – 6)

The complete question is added as an attachment
The statement is given as:
Twice the difference of a number and six
Represent the number with n.
So, the statement becomes
Twice the difference of a n and six
Twice means 2 *
So, we have
2 * difference of a n and six
Express difference as minus i.e. -
So, we have
2 * (n - 6)
Hence, the expression is written as 2(n - 6)
