Final answer:
To rewrite the expression without parentheses, distribute the negative sign to each term inside the parentheses, which results in combining like terms to get 5m - 4.
Step-by-step explanation:
To rewrite the expression 14m - (4 + 9m) without parentheses, we need to distribute the negative sign across the terms inside the parentheses. This means you will change the sign of each term inside the parentheses when you remove them.
14m - 4 - 9m = 5m - 4
We combined like terms by subtracting 9m from 14m which gives us 5m, and then we rewrote the constant -4 without any changes.
