Answer:
x = 17
Step-by-step explanation:
3(x-12)=15
->
x-12+12=5+12
√(43) = 6.55.
-3√(2) = -4.24...
√(43) > 3.6 > -3√(2)
3b^2 - x = -9b^2
x = 3b^2 +9b^2
x = 12b^2
3b^2 -12b^2 = -9b^2
hope this will help you
Actually none of them are the prime factors of 54.
A. indeed are factors, but neither of them are prime.
But you can break down A. into prime factors, 9 = 3*3, 6 = 3*2.
So now you have 3*3 * 3*2, which are all prime.
So the prime factorization of 54 is 3*3*3*2
Answer:
The system has infinite solutions
Step-by-step explanation:
For a system of two linear equations it is always true that if one equation is a linear combination of another, then the system will have infinite solutions.
Suppose we have the following system:

If there is a number n for which it is fulfilled that

Then the system has infinite solutions.
In this case the system is:

Observe that:

Then 
The system has infinite solutions
