Answer
A, B, C, D
Step-by-step solution
- Analyze the question: The question asks to identify which of the given options represent complete answers, meaning they do not have any unfilled parts or placeholders (represented by empty blue boxes in a template context). We need to examine each option to see if it's a fully formed mathematical expression or value.
- Evaluate option A: The expression is $3x^2 + 4y$. This is a complete algebraic expression. There are no empty boxes or placeholders. It represents a sum of two terms.
- Evaluate option B: The expression is $x - \frac{1}{5}$. This is also a complete algebraic expression. It represents a difference between a variable and a fraction. There are no empty boxes or placeholders.
- Evaluate option C: The expression is $(2, -4)$. This is a complete ordered pair, representing coordinates on a plane. There are no empty boxes or placeholders.
- Evaluate option D: The expression is $\sqrt{29}$. This is a complete mathematical expression representing the square root of 29. There are no empty boxes or placeholders.
- Evaluate option E: This option states "None of the above answers are complete." Since options A, B, C, and D all appear to be complete mathematical expressions or values, this option is likely incorrect.
- Conclusion: Based on the analysis, options A, B, C, and D all represent complete mathematical entities without any missing parts or placeholders. Therefore, all of them should be selected.
