4. identify the terms, coefficients, and constants in this expression: $9x - 5 + 4x + 8$

Explanation:

Step1: Identify all terms

Terms are separated by +/–: $9x$, $-5$, $4x$, $8$

Step2: Identify coefficients

Coefficients are numbers multiplied by $x$: $9$ (for $9x$), $4$ (for $4x$)

Step3: Identify constants

Constants are terms without variables: $-5$, $8$

Answer:

• Terms: $9x$, $-5$, $4x$, $8$
• Coefficients: $9$, $4$
• Constants: $-5$, $8$
