Final answer:
The simplified expression of 15x - 32 + 57 - 5 is 15x + 20, but this is not one of the provided options, suggesting there might be an error in the question.
Step-by-step explanation:
The expression we are looking to simplify is 15x - 32 + 57 - 5. To simplify the expression, we combine like terms. First, we combine the constants: -32 + 57 - 5. This can be simplified by calculating 57 - 32 which equals 25 and then subtracting 5 from 25, which gives us 20. The expression now is 15x + 20. However, none of the options provided match this expression. There may be a mistake in the question or the options provided, as the simplified expression we've found is not listed as one of the choices.
