QuestionDraw a model and write the expression for doubling the sum of 5 and 4: (5+4)×2(5+4) \times 2 or (5+4)+(5+4)(5+4)+(5+4).

Studdy Solution
To draw a model, we can use a strip diagram or bar model.For the expression (5+)×2(5+) \times2, we can draw two equal-length bars side by side, each representing the sum of5 and.For the expression (5+)+(5+)(5+)+(5+), we can draw two equal-length bars side by side, each representing the sum of5 and.In both cases, the total length of the two bars represents the final result of the operation.
