Non of the lines are the same, the equations are dependent linear equations.
Step-by-step explanation:
n! = n × n−2 × n−3 × ... × 2 × 1
(n+1)! = n+1 × n × n−2 × n−3 × ... × 2 × 1
(n+1)! = (n+1) n!
Therefore:
lim(n→∞) (n! / (n+1)!)
lim(n→∞) (n! / ((n+1) n!))
lim(n→∞) (1 / (n+1))
0
38/2 is 19
38-238-2= -202
38+238+2= 278
The solutions for 
is option 3. 
Step-by-step explanation:
Step 1:
First, we must bring the equation to the form of 
So becomes 
The value of a is the coefficient of the 
term, the value of b is the coefficient of x term and c is the coefficient of the constant term.
Comparing the above equation to 
we get 
and 
We have the formula 
Step 2:
By substituting the known values, we get
This is the third option.
