Answer:
is irrational
Step-by-step explanation:
Let us assume that is rational. Thus, it can be expressed in the form of fraction 
, where x and y are co-prime to each other.
=
Squaring both sides,
Now, it is clear that x is an even number. So, let us substitute x = 2u
Thus,
Thus, 
is even, which follows the fact that y is also an even number. But this is a contradiction as x and y have a common factor that is 2 but we assumed that the fraction was in lowest form.
Hence, is not a rational number. But is a an irrational number.

Domain: {10, 12, -8, 6}
Range: {-3, 3, -7, -1}
There is one value of <em>y</em><em> </em>for every value of <em>x</em>.
This relation is a function.
The equation will be 12a – 360 = 216. Then the value of the variable a will be 48.
<h3>What is the solution of the equation?</h3>
The solution of the equation means the value of the unknown or variable.
When you multiply a number by 12 and subtract the product from 360, the difference is 216.
Let the number be a.
Then we have the equation
12a – 360 = 216
By solving the equation, we have
12a = 216 + 360
12a = 576
a = 576/12
a = 48
