Answer:
Explanation:
Hello.
Please remember that a constant is a number without any variables next to it.
Let's search for constants in this expression.
The first term is 12. It has no variables, thus, it's a constant.
The second term is 15x. It does have a variable, thus, it's not a constant.
The third term is -16. It has no variables, thus, it's also a constant.
The 4th term is -4x (not a constant)
The last term is -10 (a constant)
I hope it helps & have an outstanding day.
