An expression can either be an equation or an inequality.
The correct classification of the terms are:
- Expression; 4x+20
- Inequality: 4x+20>40
- Equation: 4x+20=40
How to determine the correct classification
To determine the correct classification, we make use of the following highlights
- When an expression has the "=", then the expression is an equation.
- When an expression has any of the following sign ">, <, >=, <= or != ", then the expression is an inequality.
- When the expression is neither an equation nor an inequality, then it is just an expression.
Hence, the correct classifications are:
- Expression; 4x+20
- Inequality: 4x+20>40
- Equation: 4x+20=40
