Final answer:
The equivalent expression to (9+n)+14 is 23 + n, obtained by simplifying and combining like terms.
Step-by-step explanation:
The question is asking to simplify and find an expression equivalent to the given expression (9+n)+14. Since addition is commutative, meaning the order of the terms does not matter, we can simplify the expression by combining like terms. We first group the constant numbers and then leave n by itself, which gives us 9 + 14 + n. Adding the constants together gives us 23 + n. Therefore, the simplified and equivalent expression is 23 + n. This equivalent expression maintains the original meaning of adding 9 and n and then adding 14 to the result. It's simplified to its most concise form by combining like terms. This process involves removing unnecessary parentheses and performing any indicated operations to express the expression in a simpler, but equivalent, form.
