The expressions which are equivalent to neither:
and 
Step-by-step explanation:
Given the expressions:
1)
2)
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as (because when we multiply a negative sign with negative, it becomes positive.)
Similarly can be written as (because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to and
is equivalent to and .
The expressions which are equivalent to neither:
and
Answer:
The correct option is C
C) Hungary
Step-by-step explanation:
Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
So what you would do is put in the 4 where ever you see an x. so it would look like -3(4)+9y=-57 then you solve for y. and the answer is -5. Make sense?
