notice... the dog's pen perimeter, does not include the side that's bordering the garden's, since that side will use the heavy duty fence, instead of the light one
so, the sum of both of those costs, will be the C(x)
so, just take the derivative of it, and set it to 0 to find the extremas, and do a first-derivative test for any minimum
Answer:
I don't think so.
Step-by-step explanation:
1/2p-(1/4p-4)
1/2p-(1-16p/4p)
(2p-1+16p)/4p
(18p-1)/4p
2(9p-1)/4p
9p-1/2p
Answer:
8x + 9
Step-by-step explanation:
Treat the question as 2 separate brackets
First expand 3(2x + 1) :
6x + 3
Then expand 2(x + 3) :
2x + 6
Now add the two answers together and simplify :
= 6x + 3 + 2x + 6
= 8x + 9
hope this helps :)
In order to answer that question, we need to know the scale of the map.
Without that information, no answer is possible.
I think you have it in the first part of the question ... the part you decided
not to post.

OK. Now that you've provided the scale of the map,
answering the question is a piece-o-cake.
Use a proportion:
(1 inch on the map) / (4 miles on the ground) = ('x' on the map) / (17 miles on the ground)
