What's 40% of 40 please explain.

The answer would be 16. So take a look at 40%, and change it into a fraction, which is: 40/100, but can simplify to 2/5. Then multiply that fraction to 40. That is how you can get 16.
Good luck and hope I helped. :)

Answer:

x = ± $\frac{2}{3}$

Step-by-step explanation:

9x² - 4 = 0 ( add 4 to both sides )

9x² = 4 ( divide both sides by 9 )

x² = $\frac{4}{9}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{4}{9} }$ = ± $\frac{\sqrt{4} }{\sqrt{9} }$ = ± $\frac{2}{3}$
