Answer:
A
Step-by-step explanation:
12x12 = 144 per side
144x6 sides = 864
The mathematical expression of the given above is 4/y^-3 where only the denominator is raised to exponent -3. Remember that the expression x^-n may also be expressed as 1/x^n. Thus, for the given, transfer the y^-3 of the denominator to the numerator to give the final answer of 4y³.

Substitute x = 5 in the equation.

Therefore, the answer is -15 or last choice when x = 5.
