Total number of beads = 3 + 8 + 7 = 18. P(red) = total number of red/total number of beads = 3/18 = 1/6. P(blue) = total number of blue beads/total number of beads left after replacement = 8/17. P(black) = total number of black beads/total number of beads left after replacement = 7/16. Therefore P(red) = 1/6. P(blue) = 8/17. P(black) = 7/16.

Continue the pattern: 3-6,12,4,20​
Brrunno [24]

Answer:

The most likely solution sought is 13:

Beginning with 3: subtract 9, add 18, subtract 8, add 16, subtract 7, add 14, etc. Each time, reduce the number subtracted by one, and double that number to add.

So, beginning with 3: 3-9 = -6, -6+2(9) = 12, 12-8 = 4, 4+2(8) = 20, 20-7 = 13, etc.

Well, a rectangle has 4 sides and the opposite side is at an equal length so you want to do 25 in. times 2= 50 inches. Then you want to subtract the 50 inched from 64 inches which will equal = 14. Then to get the other side lengths you need to divide it my two which is 7. 
So your side lengths are seven inches. The word is side lengths.
