1. The problem is to identify the parts of the expression and equation: $-18u + -85i + -33 = -114$. 2. **Coefficient**: The numerical factor multiplying a variable. Here, coefficients are $-18$ for $u$ and $-85$ for $i$. 3. **Variable**: The symbols representing unknown values. Here, the variables are $u$ and $i$. 4. **Term**: Each part separated by plus or minus signs. Terms are $-18u$, $-85i$, $-33$, and $-114$. 5. **Constant**: A term without a variable. Constants here are $-33$ and $-114$. 6. **Expression**: A combination of terms without an equals sign. The left side $-18u + -85i + -33$ is an expression. 7. **Equation**: A statement that two expressions are equal. The entire statement $-18u + -85i + -33 = -114$ is an equation. Final answers: - Coefficients: $-18$, $-85$ - Variables: $u$, $i$ - Terms: $-18u$, $-85i$, $-33$, $-114$ - Constants: $-33$, $-114$ - Expression: $-18u + -85i + -33$ - Equation: $-18u + -85i + -33 = -114$
