Answer:
x^2 + 2xy/5 + y^2/25
Step-by-step explanation:
A= x(4x-2) then distribute the x to get A=4x²-2x
Then plug in the 8 and get A=4(8)²-2(8)
A=256-16
A=240
We know the number of all ways to take one marble and then take another marble is: 10x9=90
The first time, Jamie wants to pick a white and the ways is: 3
Now we have only 9 marble with 2 white and 7 blues, she has 7 ways to take a blue . So, she has 3x7=21 ways to take what she wants.
And we do the division 21:90=7/30. and that is the answer
