Answer:
The expression that represents the width of the office complex is 4y². The floor area of the first floor of the complex can be expressed as 24x³y^-4, and the length can be expressed as 6x - 2y³. To find the width of the complex, we need to divide the area by the length. This gives us 24x³y⁻⁴ / (6x - 2y³) = 4y².
