Final answer:
In the expression 5z + 6 + y^2, the term 5z has a coefficient of 5, the constant is 6, and the term y^2 has a coefficient of 1.
Step-by-step explanation:
The expression 5z + 6 + y^2 contains three terms: 5z, 6, and y^2.
The term 5z has a coefficient of 5, the term 6 is a constant, and the term y^2 has a coefficient of 1.
So, the correct answer is: Term: 5z, Coefficient: 5, Constant: 6, Term: y^2, Coefficient: 1 (d).
