Your answer would be - 3/10
Just by the language difference means subtract,
Y^2-25 is the difference of squares
factored it's the sum and difference of their square roots
(x+5) (x-5)
I think the answer is 700 as 700*10=7,000.
B, parallel lines run the same direction next to each other.
Even chance/possibly with all the other colors
because there is 5 of each colour making it not so likely to pull one color more then the other but less likely of not pulling that color at all
hope this helps
