Answer: r=4

What you do is subtract 12 from itself and from -24 then you have -9r=-36. Then you take -9r and divide it -9 then do the same to -36 and you get 4 :)

Enter your answer, in simplest radical form.

Alexus [3.1K]

Answer: 30x $\sqrt{2y}$

Step-by-step explanation:

$\sqrt{6x}$ x $\sqrt{15xy}$ x $\sqrt{20}$

This can also be written as :

$\sqrt{6x.15xy.20}$

= $\sqrt{1800x^{2}y}$

which could be written as :

$\sqrt{900x^{2}}$ x $\sqrt{2y}$

= 30x $\sqrt{2y}$
