Answer:
L is not valid.
Step-by-step explanation:
For any triangle, the sum of the two legs must be greater than the hypotenuse. Otherwise the two legs would not be long enough to touch.
2) 4 is not a solution.
3) -1 is not a solution.
4) 0 is a solution.
5) 0.23 is not a solution.
6) 2/3 is a solution.

The number of machines that must be made to minimize the unit cost will be 230.
<h3>How to calculate the units?</h3>
From the information, the cost function is given as C(x)=0.9x²-414x+52,794. This will be differentiated.
C(x)=0.9x²-414x+52,794
C'(x) = d/dx(0.9x² - 414x + 52,794)
= 1.8x - 414
1.8x - 414 = 0
1.8x = 414
x = 414/1.8
x = 230

He worked an 8 hour day 3 days.
Let x be the number of 8 hour days he works. Then 10-x is the number of 6 hour days he works.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms,
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
There were 3 days he worked 8 hours.
