Answer:
There are a total of 4 + r + 6 marbles in the bag
The probability of a blue is 
The probability of a red is 
The probability of choosing a blue, replacing it and then a red is
× = [tex]\frac{4r}{100+20r+ r^{2} /[tex]
Step-by-step explanation:
All you do is measure it with a ruler and for every 1 cm you get multiply it by 8.5ft.
so for example if you got 6cm then you would multiply it by 8.5ft and your answer would be 51ft.
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.
<span>2x^2 + 3x + 0=0 </span>
<span>a=2, b=3, c=0 </span>
<span>b^2-4ac (In the next step just plug in your variables) </span>
<span>3^2 - 4(2)(0) </span>
<span>9 - 8(0) </span>
<span>9 - 0 </span>
<span>Your answer=9</span>
Answer:
no
