Add or subtract.
-15mz + 5m4
A) 60z4+m5m2

To add or subtract terms with variables, we need to have the same variables raised to the same powers. In this case, we can't add or subtract the terms as they are. However, if we factor out the common factor of 5m4, we get:

15mz + 5m4 = 5m4(3z + 1)

Now we have the same variable raised to the same power, so we can add or subtract the terms. This gives us:

5m4(3z + 1) = 60z4 + m5m2

So the correct choice is A. To add or subtract monomials, we must have the same variable(s) raised to the same exponent(s). In this case, we can add the monomials because they both have the same variable "m" and the same exponent "4" on one term, and both have the same variable "z" on the other term. Therefore, we can add the coefficients: 15 + 5 = 20, and we get 20mz + 5m4. The only choice that represents this in simplified form is A.
