The probability would be split for this problem cause knowing with 20 coins , you can split that even amount ... here's what I would do..
Michelle has 20 coins , but only half of them land on heads and others on tails
As for a half , halves are always equaling to 1/2 or 50 (%) knowing we have 20 , you can evenly split that number of coins in a equal position
So ask your self .. what is half of 20? hmmm .. oh I got it , its 10! so knowing you have 20 but then later you split into half which is 10 ... meaning and knowing you have a 50% probability of getting the 20 coins hitting onto tails
hope this helps!
First of all you'll have to
Factor x^2-4x+4 = (x-2)^2
Factor x^2+10x+25 = (x+5)^2
Factor x^2+3x-10 = (x+5)(x-2)
So you'll have (x-2)^2/(x+5)^2 X (x+5)/(x+5)(x-2)
Then cancel the (x-2) and (x+5) on both sides
Thus getting the answer of x-2/(x+5)^2
or x-2/x+10+25
The correct answer is A because when you solve everything in this equation, it comes out to 7=7=7=7=7, so this is correct. Just use your calculator to solve these.
