Answer:
Two consecutive positive integers are 17 and 18. Or -17 and -18.
Step-by-step explanation:
Let the consecutive integers be x and x+1
x (x+1)=306 --> x^2 + x-306=0
x^2+18x-17x-306=0
x(x+18)-17(x+18)=0
or
(x-17)(x+18)=0
Answer:
Step-by-step explanation:
What ever one you think is better.
From the total pool of colored balls, one can choose 2 reds, 2 blacks, 3 whites, and 2 blues in

ways.
I'm assuming no ball of the same color is distinguishable from any other ball of the same color. So when I'm considering the possible arrangements, if I had lined up the ball as
red1 - black - red2 - ...
then this would be no different that
red2 - black - red1 - ...
So I now have 9 balls to arrange, which means there are

total possible permutations of them. But order among distinct colors is assumed to not matter. This means I have to divide the total number of permutations by the number of ways I could permute balls of the same color. Then there would be a total of

ways of arranging the balls I had selected.
