Translate the verbal expression below to an algebraic expression. Twice a number

  1. 2n

  2. 2 x n

  3. n + n

  4. n × 2

The correct answer is: 2n

Explanation The verbal expression "Twice a number" implies that the number is multiplied by 2, which means that the algebraic expression should include the multiplication symbol, ×. Among the choices, A is the only expression that follows this rule. B is equivalent to Option A, but not written in a standard algebraic form. C represents adding two numbers together instead of multiplying. D also represents addition instead of multiplication, but it includes the symbol for addition, +, instead of multiplication. Therefore, A is the correct answer since it aligns with the given verbal expression and follows proper algebraic notation.
