Answer:
90 engines must be made to minimize the unit cost.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
It's vertex is the point 
In which
Where
If a>0, the minimum value of the function will happen for 
C(x)=x²-180x+20,482
This means that 
How many engines must be made to minimize the unit cost?
x value of the vertex. So
90 engines must be made to minimize the unit cost.
6-3x=2x
In order to solve these, you first want to get all the variables on one side. So, you add 3x to both sides.
6=x
The answer is x=6

Answer:
11
Step-by-step explanation:
f(1) = 3(1) + 8 = 3 + 8 = 11
The answer is:
144mg
Working out/ Explanation:
13% of 300mg = 39
39 times 4 = 156
300mg - 156mg = 144mg
