Answer:

In order to maximize the last equation we can derivate the function in term of x and we got:

And setting this derivate equal to 0 we got:

And solving for x we got:

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

Step-by-step explanation:
For this case we have the following function for the profit:

And we can rewrite this expression like this:

In order to maximize the last equation we can derivate the function in term of x and we got:

And setting this derivate equal to 0 we got:

And solving for x we got:

And for this case the value that maximize the profit would be x =95 and the corresponding profit would be:

Put this into an equation. Make the missing value "x".
6x - 5 = 49
49 + 5 = 54
54 / 6 = 9
x = 9.
The missing number is 9.
Hope This Helps You!
Good Luck Studying :)
Answer:
sorry accidentally answered
Step-by-step explanation:
56 / 8 = 7
7 * 10 = 70
She would have earned $70
If the length is 7/6 the width w then the perimeter is w + (7/6)w + w + (7/6w)
= 2((7/6)w + w) = 2w + (14/6)w = (26/6)w = (13/3)w.
So the answer is the last one.
