(f+g)(x)=0
f (x) + g (x)=0

now,
substitute their values

x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0

we have to find it's zeroes (or roots) now:

x-6 =0
x = 6

x +3 =0
x = -3

Answer:

Step-by-step explanation:

We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.

<em>There are 50 in total, and 8 of them are red, so:</em>

P(red) = $\frac{8}{50}=0.16$

<em>Now we multiply this with 500 to get:</em>

$500*0.16=80$

The correct answer is A.
