8r+(12-3)p-7------>8r+9p-7
-2. Because on the number line it goes -3 -2 -1 0 1 2 3 so if you count backwards from 2 it is -2
Consider the Set A = {X | X is an even whole number between 0 and 2 } =
.
Since, whole numbers are the set of numbers starting from zero upto infinity.
Even numbers are the numbers which are exactly divisible by '2'.
So, we have to find the even whole number between 0 and 2.
Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.
Therefore, there is no even whole number between 0 and 2.
So, this set is empty.
Therefore, A = { X | X is an even whole number between 0 and 2} = 
I think The answer is 22.5
X > -2....................
