Answer:
x = 1 and x = -3
Step-by-step explanation:
We need to solve the given equation.

Taking all terms together,

So, the solution of the above equation is x = 1 and x = -3.
Answer:
Zero
Step-by-step explanation:
The probability of the ball being red after first selection is = (r) ÷ (r+b)
The probability of the ball being blue after first selection is = (b) ÷ (r+b)
If the ball selected is red, the total number of balls after its returned together with m number of red balls is = r+b+m
The probability of the selection doesn't depend on the second selection, hence condition probability is zero.
However the probability of the second selection depends on the first selection.
Answer:
C. Apply the distributive property to get 4x-12=9.
Step-by-step explanation:
To get x out of the parentheses, you have to use the distributive property by multiplying both x and -3.
Hope this helps you :)

Answer:

Step-by-step explanation:
(f g)(x) is equal to f(x) times g(x). So you just need to multiply both of the equations together. Use the foil method to multiply (x+2)(x-4)
