Answer:x+12
Step-by-step explanation:
A prime number can only be divided by one oritslef and a composite number can bedivided by other njmbers.
Measures of angles 2, 3, 4, added equal 180
Answer: The journey took 4 hours and 15 minutes.
R(x) = 60x - 0.2x^2
The revenue is maximum when the derivative of R(x) = 0.
dR(x)/dx = 60 - 0.4x = 0
0.4x = 60
x = 60/0.4 = 150
Therefore, maximum revenue is 60(150) - 0.2(150)^2 = 9000 - 4500 = $4,500
Maximum revenue is $4,500 and the number of units is 150 units
