Final answer:
The expression given is a polynomial, and each term is named by its degree and coefficient, ranging from the eighth-degree term to the constant term.
Step-by-step explanation:
The expression 9x8-3x7+11x5-4x+29 is a polynomial in one variable. Each term in the polynomial is named by its degree and coefficient. The term 9x8 is called the eighth-degree term with a coefficient of 9. The term -3x7 is the seventh-degree term with a coefficient of -3. The term 11x5 is the fifth-degree term with a coefficient of 11. -4x is the first-degree term with a coefficient of -4, and finally, 29 is the constant term or zero-degree term.
