Answer: False
Explanation: In math, “like terms” refer to any terms that share the same variable, or lack of. In the scenario given to us, we are asked to determine if 9z and 9x are like terms. Though both numbers have a constant of 9, this will not help us in any way, as we are to look at the variable. Since one variable is z and the other is x, 9z and 9x are not like terms.
