What is the perimeter of the rectangle? (read comments)

OpenStudy (anonymous):

Well perimeter is adding up all of the sides

OpenStudy (mokeira):

P=2(L+W) \[P=2(3\sqrt{2}+5+\sqrt{2})\] \[P=2(4\sqrt{2}+5)\] \[P=8\sqrt{2}+10\]

@Mokeira is smart

OpenStudy (mokeira):

hahaha lol no..i just did what you said @kayla_renae

OpenStudy (anonymous):

Thank you, @Mokeira What if the square root has numbers like this?

OpenStudy (mokeira):

\[A=L \times W\] \[A=2\sqrt[3]{12} \times (4+\sqrt[3]{18})\] \[A=8\sqrt[3]{12}+2\sqrt[3]{216?}\] \[A=8\sqrt[3]{12?}+12\]

OpenStudy (mokeira):

hope you understand each step

OpenStudy (anonymous):

Yes, thank you!! Sqr rts always trip me up. Can you help with two more? @Mokeira

OpenStudy (anonymous):

@texaschic101 do you know?

OpenStudy (mokeira):

\[A=\pi r^2\] \[1000\pi=\pi r^2\] \[r^2=\frac{ 1000\pi }{\pi }\] \[r^2=1000\] \[r=\sqrt{1000}\] \[r=10\sqrt{10}\]

OpenStudy (anonymous):

Thank you!!! I can't figure out how to plug this in @Mokeira

OpenStudy (mokeira):

\[v=s^3\] \[1372=s^3\] \[s=\sqrt[3]{1372}\] \[s=7\sqrt[3]{4}\]
