The volume is 180.32 because if u multiply those three numbers u get 180.32. Also, what do u mean by SA
x=2 is only solution while x=1 is extraneous solution
Option C is correct.
Step-by-step explanation:
We need to solve the equation
and find values of x.
Solving:
Find the LCM of denominators x-1,x and x-1. The LCM is x(x-1)
Multiply the entire equation with x(x-1)

Now, factoring the term:

The values of x are x=1 and x=2
Checking for extraneous roots:
Extraneous roots: The root that is the solution of the equation but when we put it in the equation the answer turns out not to be right.
If we put x=1 in the equation,
the denominator becomes zero i.e
which is not correct as in fraction anything divided by zero is undefined. So, x=1 is an extraneous solution.
If we put x=2 in the equation,


So, x=2 is only solution while x=1 is extraneous solution
Option C is correct.

Step-by-step explanation:
You can obtain any two points on the graph of
and use it to draw its graph.
When x=0, 
So you plot (0,2)
When x=1, 
You again plot (1,-71).
With a straight edge you can now draw a straight line through the two points.
