Answer:
x=2
Step-by-step explanation:
We know the only number that gets us back to 0 after subtracting 4 is 4, because 4-4=0. The square root of 4 is 2. Hope my explanation wasn't too confusing!
2²=4
4-4=0
142
1•4= 4
5•5= 25
1•11= 11
6•18= 102
102+11+25+4= 142

Answer: Choice B</h3>

which is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))
=====================================
Explanation:
The LCD is (x+6)(x-2) which is the factorization of x^2+4x-12, and that is the denominator of the first fraction. The first fraction has the LCD already. The second fraction does not. It has (x+6) but it is missing (x-2).
We multiply top and bottom of the second fraction by (x-2) to get the second fraction to have the LCD.
turns into 
------
So,



This is the same as x/((x+6)(x-2)) - 3(x-2)/((x+6)(x-2))
Note the parenthesis around "(x+6)(x-2)"
Instead of x/(x+6)(x-2) you should write x/( (x+6)(x-2) ) to ensure that all of "(x+6)(x-2)" is in the denominator.
Take 4.51 divided by .45
