Identify the following as an expression or an equation.(4 points)

Question

Expression Equation
24x3=18

2x2+3x+5

7x+3=1

44⋅−2x

Answer 1

To identify each item as an expression or an equation:

1. 24x³ = 18 - Equation (because it contains an equals sign)

2. 2x² + 3x + 5 - Expression (there is no equals sign)

3. 7x + 3 = 1 - Equation (because it contains an equals sign)

4. 44 ⋅ −2x - Expression (there is no equals sign)

So, to summarize:

• Equation: 24x³ = 18; 7x + 3 = 1
• Expression: 2x² + 3x + 5; 44 ⋅ −2x
