Answer:
yes my answer is yes kind sir
5x-3x^2/2x^4 =x(5-3x) / 2x.(x^3), simplified by x, we have <span>5-3x/2x^3, (x≠0)
</span>so the answer is <span>C.5-3x/2x^3, (x≠0)</span>
We need to find the maximum (Vertex of the function)
Let:
L = Length = 1500 - 2x
W = Width = x
The area is given by:

We can find the maximum using the following formula:

Evaluate the area for the value we found previously:

The largest area that can be enclosed is 281250m²
