Eddie is correct about his prediction. A coin has two sides, one head, one tail, so there is a 50% chance that it will land heads every time Eddie flips the coin. I would tell Eddie that his prediction is reasonable and mathematically correct.
        
             
        
        
        
Answer:
y= -9+√122, or -9 - √122
Step-by-step explanation:
You have to solve the equation for y to find each variable of the quadratic and applying the quadratic formula.
after solved, I got the answer as decimal, 
y = 2.0453610..... 
i simpler form : y = 2.05
Also, an answer can be y= -9+√122, or -9 - √122

3 × 100 = 300
the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example
3 × 10000 if you would just take out the zero's
 it would look like this. 3 × 1
 the answer of course would be 3 then you can put the zero's back in the answer (30000)
 at least that's how I understood it
 3 × 100 =
 3 × 1(00) =
 -->
 -->
 (00)
 3 × 1(00) = 3
 3 × 100 = 300
