Step-by-step explanation:
X^2 +4X +4=12 subtract the 12 from both sides
X^2 +4x-8= 0
now factor if possible since this equation is not factorable you can use the quadratic formula
The probabilities of picking a red, blue, and yellow marble must be equal to 1. so
P(R)+P(Y)+P(B)=1
1/6+1/2+P(B)=1 making all terms have a common denominator of 6 we have:
1+3+6P(B)=6
4+6P(B)=6
6P(B)=2
P(B)=2/6
P(B)=1/3
I took a picture so you can see the steps I took! hope that helps!
