The answer: 0, 4/5 and 5
Explanation: first, we factor out 2x and get: 2x(5x^2-29x+20)=0
In order for this equation to be equal to zero, either 2x must equal to zero or (5x^2-29x+20) must equal to zero
Having said that, if:
2x = 0
X=0
If:
(5x^2-29x+20) = 0
X=4/6, x=5
Answer:
there

Answer:
Step-by-step explanation:
First find out how many marbles is in the box.
1 r + 1 b + 4 g = 6 marbles
4g/6
2/3 is the probability
So we have lengths a and b and are given:
2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272
plug in one into the other:
(33-b)b = 272 => -b^2 +33b - 272 = 0
Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.
So a=16 and b=17 or vice versa.
