I believe it’s 1/2 because 3/6 chances it’ll be a red marble. And 3/6 is also 1/2
Step-by-step explanation:
6 (x+5 )^2 +5(x+5)-4=0
let x+5= y
6y^2 + 5y - 4=0
6y^2 + 8y - 3y-4 =0
2y (3y+4) - 1 (3y+4)=0
(2y-1)(3y+4)=0
2y-1=0 or 3y+4=0
y=1/3 or -4/3
Recall that x+5=y
When y=1/3
x+5=1/3
x= -14/3
when y= -4/3
x+5=-4/3
x = -11/3
10.
GCF=3x^2y
so
3x^2y(2x-3y+1)

11.
what 2 numbers multiply to get 4 and add to 4?
2
(c+2)(c+2) or
(c+2)^2
2nd option
Answer: 
Step-by-step explanation:
Number of persons said it is legal to text while driving = 8
Number of persons said it is illegal to text while driving = 804
Total persons sampled = 804+8 = 812
Since probability =
The probability of randomly selecting someone who believes it should be legal to text while driving = 
Required probability =
