Answer:
C. x + 9 = 11
Step-by-step explanation:
We are trying to identify which of the equations does not match with the others. In this case, solve for x in each equation: 
Option A): 
6 + x = 9
Subtract 6 from both sides: 
6 (-6) + x = 9 (-6)
x = 9 - 6
x = 3
Option B): 
15 = x + 12
Subtract 12 from both sides: 
15 (-12) = x + 12 (-12)
15 - 12 =  x
x = 3
Option C): 
x + 9 = 11
Subtract 9 from both sides: 
x + 9 (-9) = 11 (-9)
x = 11 - 9
x = 2
Option D): 
7 + x = 10
Subtract 7 from both sides: 
x + 7 (-7) = 10 (-7)
x = 10 - 7
x = 3
---------------------------------------------------------------------------------------------------------
As you can tell, all the equations end with x = 3 as there answers except C. x+9=11, making (C) your answer.

The product of √3 and 5√3  in its simplest form is 15.
<h3>What is a rational number?</h3>
A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.
It can be a/b of two integers, a numerator a, and a non-zero denominator b.
To determine the product of √3 and 5√3
So, (√3 )(5√3)
⇒ 5 (√3 )(√3 )
⇒ 5(3)
⇒ 15
The result is rational because 15, can be expressed as a ratio of two integers can be 15/1 of two integers, a numerator 15, and denominator 1 ( which is a non-zero).
Thus, the result is rational.
