Final answer:
The expression -47 - 2m + 11m simplifies to -47 + 9m by combining like terms. The correct answer, -47 + 9m, does not match any of the provided options.
Step-by-step explanation:
The expression -47 - 2m + 11m can be simplified by combining like terms (the terms containing the variable m). To simplify the expression, you add the coefficients of m together. The terms with m are -2m and 11m, and when you combine them, you get 9m (11m - 2m = 9m). So the expression becomes -47 + 9m. Finally, you are left with two separate terms, -47 and 9m, which cannot be combined further because they are not like terms. The answer is therefore choice (d) -28 + 3m, which is similar but incorrect. The correct answer is not listed as an option, but if it were, it would be -47 + 9m.
