Question

Evaluate, if x = -12, y=-4, and z is = 9:
a) -55
b) -25
c) 45
d) 15

Answer 1

The question lacks a clear expression or algebraic problem to solve using the given values for x, y, and z. Therefore, an evaluation cannot be provided based on the current information.

Step-by-step explanation:

The student is asking to evaluate an expression given the values x = -12, y = -4, and z = 9. However, the provided options (a) -55, (b) -25, (c) 45, (d) 15 do not correspond to a clear algebraic expression involving x, y, and z that we can evaluate.

The various numbers and formulas provided in the question seem unrelated to a specific problem that needs to be solved using the given values of x, y, and z. Without a clear problem to solve or an expression to evaluate with these variables, we cannot provide an answer to the question as it stands.
