Final answer:
The missing number in the expression 3(m 3) = __m+__ is 9.
Step-by-step explanation:
The missing number in the expression 3(m 3) = __m+__ is 9.
Let's break it down step-by-step:
Step 1: Simplify 3(m 3) using the distributive property. Multiply 3 by the terms inside the parentheses: 3 * m = 3m, and 3 * 3 = 9. The expression becomes 3m + 9.
Step 2: Set the expression equal to __m+__. So, 3m + 9 = __m+__.
Step 3: The missing number in the first blank is 3 (since we have 3m) and in the second blank is 9 (the same number we obtained from simplifying 3(m 3)).
Therefore, the missing number in the expression is 9.
