0 for j to get 1
1 for j to get -2
2 for j to get 4

1. how many times 47 fits on 985? 20×47=940
try higher: 47×21=987. So use 20. subtract 985-940=45. how many times does 47 fit on 45? 0 so the answer should be 20 remainder 45
Since you have 8 marbles of a color other than white, and only two white marbles your chance of getting a white marble at random is 2/10.
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
