Final answer:
The polynomial 4x-6+8r-12 has a degree of 1, a coefficient of -6 for the x term, and a coefficient of 8 for the r term.
Step-by-step explanation:
To determine which statements are true about the polynomial 4x-6+8r-12, we can analyze each statement:
- A) The degree of a polynomial is the highest power of the variable. In this case, the highest power is 1, since all the terms have x and r to the power of 1. Therefore, Statement A is true.
- B) The constant term in a polynomial is the term with no variable. In this case, the constant term is -12. Therefore, Statement B is false.
- C) The coefficient of a variable term is the number multiplied by the variable. In this case, the coefficient of the x term is -6. Therefore, Statement C is true.
- D) The coefficient of a variable term is the number multiplied by the variable. In this case, the coefficient of the r term is 8. Therefore, Statement D is true.
Based on the analysis, Statements A, C, and D are true.
