A parallelogram has 4 sides.
So, we divide 72, the meters of the parallelogram. = 18
Now, the length is 4 more, so we add. 18+4=22
The length is 22.
Now, both lengths are 22, so double is 44; subtract 44 from 72. 72-44=28
In conclusion, we divided 28 by 2 to get the width of both sides.28/2=14
The width is 14.
Answer:
260 machines for minimum cost.
Step-by-step explanation:
c(x) = 0.3x^2 - 156x + 26.657
Finding the derivative:
c'(x) = 0.6x - 156
0.6x - 156 = 0 for maxm/minm cost.
x = 156 / 0.6
= 260
The second derivative is positive (0.6) so this is a minimum.

Step-by-step explanation:
(9 + radical - 4) - (5 + radical - 16)
9 + radical - 4 - 5 - radical + 16
9 - 4 - 5 + 16 + radical - radical
= 16
Answer:
Step-by-step explanation:
120 x .6 =72
120-72 = 48
48x .6 = 28.8
