Step-by-step explanation:
Hello,
We need to work a little bit of the expression to see if we can simplify.
Do you remember this formula?
for any a and b reals, we can write

We will apply it.
For any x real number different from 3 (as dividing by 0 is not allowed)

So the winner is C !!
Hope this helps.
Do not hesitate if you need further explanation.

option: B is the correct answer.
B. complex numbers.
<h2>
Step-by-step explanation:</h2>
We know that a complex number is always written in the form of :
a+ib
where a and b are real numbers and i is the square root of -1.
i is called an imaginary number.
If a>0 and b>0 then the point lie in the first quadrant.
if a>0 and b<0 then the point lie in the fourth quadrant.
if a<0 and b>0 then the point lie in the second quadrant.
if a<0 and b<0 then the point lie in the third quadrant.
B is the correct answer to the following questions and
Answer:
See below.
Step-by-step explanation:
Convert to decimal form
7 3/5 = 7.6
7 7/10 = 7.7
10 2/5 = 10.4
8 1/2 = 8.5
So the answer is
7 3/5 , 7 7/10, 8.3, 8.1/2, 10.2 10 2/5, 11.1.
