To identify each item as an expression or an equation:
1. **2x^2 + 3x + 5** - **Expression** (This is a polynomial and does not contain an equality.)
2. **44 * (-2^x)** - **Expression** (This is a mathematical expression involving multiplication and exponentiation without an equality.)
3. **7x + 3 = 1** - **Equation** (This is an equation because it has an equality sign.)
4. **24x^3 = 18** - **Equation** (This is also an equation because it has an equality sign.)
So the classifications are:
- Expressions: 2x^2 + 3x + 5; 44 * (-2^x)
- Equations: 7x + 3 = 1; 24x^3 = 18
