  • Question 15 (request help)

    Sense or Nonsense Peter and Jade are using what they know about properties to write an expression equivalent to \(2\times(\text{n} + 6) + 3\). Whose answer makes sense? Whose answer is nonsense? Explain your reasoning.

    Peter's Work

    Expression : \(2\times(\text{n} + 6) + 3\)

    Associative Property of Addition : \(2\times\text{n} + (6 + 3)\)

    Add within parentheses : \(2\times\text{n} + 9\)

    Multiply : \(2\text{n} + 9\)

    Jade's Work

    Expression : \(2\times(\text{n} + 6) + 3\)

    Distributive Property : \((2\times\text{n}) + (2\times6) + 3\)

    Multiply within parentheses : \(2\text{n} + 12 + 3\)

    Associative Property of Addition : \(2\text{n} + (12 + 3)\)

    Add within parentheses : \(2\text{n} + 15\)

     

    For the answer that is nonsense, correct the statement.
