Step-by-step explanation:
A polynomial is the sum of terms with variables having positive integer exponents. Coefficient numbers need not be integers.
The term 3/x^4 = 3x^-4 is not such a term, so the expression containing it is not a polynomial.
We know:

and

These expressions have an
term in common. We can combine them if we can find forms of the expressions in terms of
:


Now, because
(by the reflexive property), we can write:

This is our answer, A.
Answer: The answer is 
Step-by-step explanation: Given that a school wants to put on a dance recital. The programs of Middle school dancer will be short of 4 minutes each and programmes of High school performers will be long of 7 minutes each.
Number of middle school dances is "M" and number od high school dances is "H".
Since there cannot be more than 10 dances all together, so fisrt inequality can be written as

Also, the entire recital must take maximum 90 minutes, so the second inequality can be written as

Thus, the pair of inequalities is
