(Second-First)/First x 100 eg What's the percentage difference between 15 and 20? (20-15)/15 x 100 = 5/15 x 100 = 33.33 %

Yes. 4x means 4 multiplied by x. x4 means x multiplied by x multiplied by x multiplied by x.
NB 3,9,21,39,63. We note that #1;The difference between 3 & 9 = 6 #2 ;The difference between 9 & 21 = 12 ( 2 x 6) #3 ; The difference between 21 & 39 = 18 ( 3 x 6) #4 ; The difference between 39 & 63 = 24 ( 4 x 6) So it follows #5 ; The difference between 63 & X = ( 5 x 6 = 30 ) So 63 + 30 = 93 The answer !!!!!

-15
2(25-15)=2 x 10=20
To find the difference between 26 and 15, you would subtract 15 from 26 to get 11.
the difference between a number and 3 is
The main difference between light and x-rays is that x-rays are radiation.
There is only one solution: x = 15. Consequently the remainder of the question is nonsense.
The difference between two numbers is the biggest minus the smallest, in this case 15-1 = 14
There is no difference between L x W and W x L For example if L = 5 and W = 3 L x W -> 5 x 3 = 15 W x L -> 3 x 5 = 15
