c. Mrs. Tran figured out how many flowers she planted.

Her work is shown in the box below. Would Mrs. Tran get the same result if she multiplied 5 Ã— 4? Explain why or why not.

Yes, Mrs. Tran get the same result if she multiplied 5 Ã— 4,

Explanation:

Mrs. Tran worked as (3 Ã— 4) + (2 Ã— 4) = 12 + 8 = 20, and Mrs. Tran got the same result if she multiply 5 Ã— 4 = 20, because in the equation both 3 and 2 are multiplied by 4.

So we add 3 and 2 first we get 5 and multiply by 4, So the result remains same 20 for 5 Ã— 4 also.
