Answer:
B. Multiplication or Division property of equality
Step-by-step explanation:
Both sides of the equation have been multiplied by -1. The multiplication property of equality tells you that multiplying both sides of the equation by the same number does not change the truth of the equation (and the variables retain their values).

just did the test
Answer:
-2
Step-by-step explanation:
Let's plug your functions f(x)=x^2-2x and g(x)=6x+4 into (f+g)(x)=0 and then solve your equation for x.
So (f+g)(x) means f(x)+g(x).
So (f+g)(x)=x^2+4x+4
Now we are solving (f+g)(x)=0 which means we are solve x^2+4x+4=0.
x^2+4x+4 is actually a perfect square and is equal to (x+2)^2.
So our equation is equivalent to solving (x+2)^2=0.
(x+2)^2=0 when x+2=0.
Subtracting 2 on both sides gives us x=-2.
