Answer:

And we can solve for y and we got:

And using condition (1) we can solve for x and we got:

So then the minimum cost for this case would be:

Explanation:
For this case the graph attached illustrate the problem for this case
We know that the total area is 60000, so then we have:

If we solve for x we got:
(1)
Now we can define the cost function like this:


We can use the condition (1) and if we replace in the cost function we have:

Since we need to minimize the cost, we can derivate the function in terms of y and we got:

And we can solve for y and we got:

And using condition (1) we can solve for x and we got:

So then the minimum cost for this case would be:

Answer:
(C) Pepin The Short
Explanation:
In 741AD, Pepin took over from his father as Mayor of the Palace. He ruled alongside his elder brother.
In 743AD, Pepin and his brother chose Childeric to be the <em>apparent</em> King of the Franks. Both brothers still wielded the functional power to the throne. Childeric was just to 'appear to be' the King (unknown to him though).
In 747AD, Pepin's brother stepped down (intentionally and on his own accord). Pepin then became the only ruler of the entire Frankish territory.
In 751AD, Pepin, without full support from his clan, lured Childeric into monastery in order to remove him as the 'face of Francia'.
Pope Zacharias helped Pepin to be proclaimed King of the Franks, against all opposition.
