Hello, please consider the following.
We will multiply the numerator and denominator by
to get rid of the root in the denominator.
First of all, we cannot divide by 0, right? So, we need to make sure that the denominator is different from 0.
We need to take any x real number different from 8/3 then and simplify the expression.
Let's do it!
Thank you
The best answer here would be choice B
POINT C..............................................................
The square (call it 
) has one vertex at the origin (0, 0, 0) and one edge on the y-axis, which tells us another vertex is (0, 3, 0). The normal vector to the plane is 
, which is enough information to figure out the equation of the plane containing :
We can parameterize this surface by
for 
and 
. Then the flux of 
, assumed to be
,
is
To find perimeter you add up all the sides so 5cm+6cm+17cm+8cm. This will get you 36cm.
