$\frac{3x+12}{x+7}$

Answer 2

The text "<0" appears to be an HTML or XML escape sequence for the less-than symbol ("<") followed by the number zero ("0"). In HTML or XML, certain characters have special meanings, so they need to be escaped when used as literal text.

In this case, "<" represents the less-than symbol ("<"), and "0" is just the number zero.

If you are encountering this text in a web page or an XML document, it's likely that it's part of a code snippet or some form of markup. If you have a specific context or question related to this text, please provide more information, and I'll be happy to assist you further.
