Ayellow ribbon is 7 centimeters long. a blue ribbon is 4 times as long as the yellow ribbon. how much longer is the blue ribbon than the yellow ribbon?

21cm longer.

Step-by-step explanation:

1. Y/R = 7cm, B/R = 7(4)cm

2. B/R = 28cm

3. 28cm - 7cm: as you are trying to find out how longer the b/r is relative to the y/r.

4. 28 - 7= 21cm.

In conclusion, the blue ribbon is longer than the yellow ribbon by 21cm.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
