How do I do this derivation step? I don't understand why there is equality. The derivation is from my textbook.

$mg-m\left(\frac{g}{1+\frac{M}{2m}}\right)=\frac{mg}{1+\frac{2m}{M}}$

I got

$V=27$

$v={x}^{3}$, which x=3 inches

$dV=3{x}^{2}\phantom{\rule{thinmathspace}{0ex}}dx$

$0.027=27dx$

dx=+2 and −2

But I am not sure what the answer of this question is.

Getting your pre Algebra solved becomes much easier when you have all the answers to your questions by taking a closer look at the various examples dealing with Pre-Algebra subjects. We have intentionally collected the list of pre-algebra equations and various solving equations with decimals problems to help you see various examples that explain how certain solutions are found. Still, if something sounds unclear or you are concerned about some solution that has been provided, approach pre-algebra with reverse engineering approach (going backwards).
