Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
It's a square number. Square numbers have a factor pair that is the same number twice. When listed, that number occurs once.
three times a number decreased by eleven
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
Because the square root isn't listed twice.
x=-3 or x=5
2*24.5 = 49
simply see what you can multiply twice to get the number under the square root sign.
One of the factor pairs for a square number will be the same number twice. When you list the factors, you only need to write that number once. That will leave you with an odd number of factors.
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
To find the square root of a number you multiply that number by it self twice.(example) the square root of 9 ? the square root of nine is 81 as 9X9=81. square root of 4 ? th square root of is 16 as 4X4=16.
Twice. a*a is a squared.
The square root of 10 times the square root of 10 = 10
The difference between a number x and twice y is equal to fifteen.
x / (2y - 7)
