$\bf \textit{recall that }i^2=-1\\\\
-------------------------------\\\\
-2i\sqrt{-12}\quad 
\begin{cases}
12=2\cdot 2\cdot 3\\
\qquad 2^2\cdot 3
\end{cases}\implies -2i\sqrt{-1\cdot 2^2\cdot 3}
\\\\\\
-2i\sqrt{-1}\cdot \sqrt{2^2}\cdot \sqrt{3}\implies -2i\cdot i\cdot 2\cdot \sqrt{3}\implies -4i^2\sqrt{3}
\\\\\\
-4(-1)\sqrt{3}\implies 4\sqrt{3}$

Plz help me in my algebra homework!

3(m - 2) - 4>= 7m + 4
Use distributive property
3m - 6 - 4>= 7m + 4
Subtract 7m from both sides
-4m - 6 - 4>= 4
Add 6 to both sides
-4m - 4>= 10
Add 4 to both sides
-4m>= 14
Divide both sides by -4 so that the only thing remaining on the left side is the variable m.
Final Answer: m<= -14/4 or 3.5 or 3 1/2 *All the answers are equivalent to each other.
