Pie

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)
<h3 /><h3>How to determine the algebraic expression?</h3>

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)
