Postulate, because we just assume that it is a true fact.
Answer:

Step-by-step explanation:
Given the equation:

To find:
The solutions of given equation in the range [0, 2
) i.e. 0 can be in the answer but
can not be there in the answer.
Solution:
Taking
common, we get:

The solutions can be given as:
OR 
Let us solve both the equations one by one:
First equation:

Second equation:

Therefore, the answers as a comma separated list are:

Answer:
Step-by-step explanation:
Just remember area equals length times width it’s like a window to a door etc!!
Answer :
and 
Greatest common factor of 
If we are able to factor out
from each option then that would be our answer.
Lets check with each options
(a)
, we cannot take out 5.
(b)
, We can take out common factor and it can be written as 
(c)
, we cannot take out n^2 because we have only 'n'
(d)
, We can take out common factor and it can be written as 
(e)
, we cannot take out 5 because we have 24
So answer is (b) and (d)
