SQRT(X) * SQRT(X) = X

The sum of the degrees of any regular polygon with number of sides n is equal to (n - 2) x 180. Therefore, the sum of the internal angles in a decagon is equal to (10 - 2) x 180 = 1440 degrees.

X is greater than 5. If X were equal to 5, X-5 would be 0 which has no real square root. If X were 4, X-5 would be -1 which has no real square root, and so on.

In that case, x must be equal to zero. (0)

To calculate square feet you need both a length and a width.1 mile is equal to 5,280 linear feet. One square mile (1 mile x 1 mile) is equal to 27,878,400 square feet.

No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one plus the square root of three.

This depends on what "x" is. The sum of the first x odd numbers is equal to x^2 or x*x.
