Final answer:
There's not enough information provided in the question to determine which expressions are equivalent to 512.58. Without additional context or explicit numerical expressions, we cannot confidently identify equivalent expressions.
Step-by-step explanation:
The question asks which expressions are equivalent to 512.58. However, the information provided does not contain direct expressions or formulas that can be used to determine equivalency to 512.58. Due to this, there's not enough relevant information to identify which expressions could be equivalent without additional context or missing numerical expressions.
