First we have to find derivative of f(x):
For x=2 we have:
Now, 
Hence, the answer is A) 2
Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
Answer: 15 inches
Step-by-step explanation:
Since the box must be square, we find the Lowest common multiple of 3 and 5, which is 15
A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
