Answer:
0
Step-by-step explanation:
f(x) = 2/5(6 - x)²
f(6) = 2/5[6 - (6)]²
f(6) = 2/5(0)²
f(6) = 0
 
        
             
        
        
        
So here are your variables:
# of adult tickets= x
# of student tickets 2x
so x+2x= 246 and solve
3x=246
x=82 adult tickets were sold

Proof by induction
Base case:
n=1: 1*2*3=6 is obviously divisible by six. 
Assumption: For every n>1 n(n+1)(n+2) is divisible by 6.
For n+1:
(n+1)(n+2)(n+3)=
(n(n+1)(n+2)+3(n+1)(n+2))
We have assumed that n(n+1)(n+2) is divisble by 6.
We now only need to prove that 3(n+1)(n+2) is divisible by 6.
If 3(n+1)(n+2) is divisible by 6, then (n+1)(n+2) must be divisible by 2.
The "cool" part about this proof. 
Since n is a natural number greater than 1 we can say the following:
If n is an odd number, then n+1 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted. 
If n is an even number" then n+2 is even, then n+1 is divisible by 2 thus (n+1)(n+2) is divisible by 2,so we have proved what we wanted. 
Therefore by using the method of mathematical induction we proved that for every natural number n, n(n+1)(n+2) is divisible by 6. QED.
 
        
             
        
        
        
Answer:
b=42 degrees
c= 138 degrees
Step-by-step explanation:
B and the 42 degrees shown are congruent angles so therefore both are 42 degrees
To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore
subtract 180 with 42 to get Angle C
180-42= 138
