The difference between a number x and twice y is equal to fifteen.
Twice the difference between a number and thirteen can be written as 2 (b - 13) Five more than twice the difference between a number and thirteen can be written as 2 (b - 13) + 5. The algebraic expression is 2 (b - 13) + 5.
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
If you mean the difference between -11 and 2*(-11), then it's 11.
twice the difference of three times a number and eight
It is abs(5 - 2n) = 1
5 - 2n = 1 4 = 2n n = 2
let x = number 2x-16 = 42 2x = 58 x = 29
I believe you mean molarity. Molarity is a unit of concentration. So if the number is twice as big...
No it is not. A Square number is one that can be expressed as the product of the same number twice. Ex: 49 is a square number 7 * 7 or 72
It does not mean anything at all. "Twice a number" is only one number while "the difference" must refer to two numbers, not just one.
One number is eight more than twice another if their difference is 25. The larger number is 42
7*(2*x - 16), or maybe 7*| 2*x - 16 |. It depends on if you want to keep the 'difference' to be a positive number.
I don't think there is a difference.

|5n - 2n|
2(n - 11)
Because the square root isn't listed twice.
