C. -4 because you factor and add like terms
Hello Alexgator88,
If there are four sections of rope and each piece is 16 inches long then we know that 16 times 4 is 64.
So your answer is 64 inches long.

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
