Match the terms to their definition. 1. algebraic expression a letter or symbol used to represent 2. evaluate 3. substitute to find the numerical value of 4. variable \( \square \) a mathematical expression containing one or more variables

Let's match the terms to their definitions: 1. **algebraic expression** - a mathematical expression containing one or more variables. 2. **evaluate** - to find the numerical value of. 3. **substitute** - a letter or symbol used to represent. 4. **variable** - a letter or symbol used to represent. So the correct matches are: - 1 → 4 - 2 → 3 - 3 → 1 - 4 → 2 Here’s the final matching: 1. algebraic expression → a mathematical expression containing one or more variables. 2. evaluate → to find the numerical value of. 3. substitute → a letter or symbol used to represent. 4. variable → a letter or symbol used to represent.
