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

They are the same amount. 0.5g is equal to 500mg.
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.
No, 1000mg = 1 gram
325mg is 3,25 and 5gr is 500mg.
0.5g=500mg
It is equal to -2.
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
5g is equal to 5000mg so the answer is 5g
500mg = 0.5 grams
