You can look up "trigonometric identities" in Wikipedia.Cos(2x), among other things, is equal to (cos x)^2 - (sin x)^2 If you meant cos squared x, or (cos x)^2, that is equal to (1 + cos(2x))/2
It is x*sqrt(x) or x^(3/2)
If: 6x = 12 Then: x = 2

No. 500mg = 0.5g ; 5g = 5000 mg
1g = 1000mg 500mg x 1g/1000mg = 0.5g
2 x 2 x 2 x 7 x 7 is equal to 2 cubed times 7 squared. 2 cubed is equal to 8, and 7 squared is equal to 49. Therefore, 2 x 2 x 2 x 7 x 7 is equal to 8 x 49 = 392.
It is equal to -2.
0.5g=500mg
325mg is 3,25 and 5gr is 500mg.
No, 1000mg = 1 gram
only when x is equal to 2
I assume you mean (x+10)(x+2) This would equal x^2+12x+20 x^2 means x squared
No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
(2 x 2 x 2 x 2 x 2 x 2) = (2)6 = 64
that depends on what that expression is equal to. If you are asking what x equals if "-x-2 = 0" for example, then the solution would be: -x-2 = 0 -x = 2 add 2 to both sides x = -2 multiply both sides by negative 1 - solved If, however, -x-2 does NOT equal zero, then this solution is incorrect. -x - 2 equal to zero, because you found that the value of x is a negative number, x = -2, and the opposite of x is a positive number, -x = -(-2) = 2. Thus -x - 2 = -(-2) - 2 = 2 - 2 = 0 If this is not a maths question, then SE made it X-2 instead of XI because X-2 was a continuation of X, instead a new universe like they usually have when they change the Roman numeral.
