I did my own work for this problem, and my answer kept coming out to 90.5 :( Help and explain?

HI!!

OpenStudy (anonymous):

I'll fan and medal

OpenStudy (anonymous):

Hi!

OpenStudy (misty1212):

from -4 to 4 is right 8 from -2 to 6 is up 8

|dw:1425610068411:dw|

OpenStudy (misty1212):

use pythagoras to find the distance

OpenStudy (anonymous):

\[8^{2}+ 8^{2}= c ^{2} \]

OpenStudy (anonymous):

\[64^{2}+64^{2}=c ^{2}\]

OpenStudy (anonymous):

\[4096+ 4096=c ^{2}\]

OpenStudy (anonymous):

\[8192=c ^{2}\]

OpenStudy (anonymous):

\[\sqrt{8192}= c ^{2}\]

OpenStudy (anonymous):

\[90.5=c ^{}\]

OpenStudy (anonymous):

That's all my work, and I dont know how to get any of the answer choices

OpenStudy (anonymous):

@misty1212

OpenStudy (misty1212):

is one answer choice \(8\sqrt2\)?

OpenStudy (misty1212):

btw \(8^2=64\) not \(8^2=64^2\)

OpenStudy (anonymous):

OpenStudy (anonymous):

these are the answers and I didn't mean to

OpenStudy (anonymous):

@iambatman

OpenStudy (misty1212):

\[64+64=128\] so \[\sqrt{128}\]

OpenStudy (anonymous):

why do you add it?

OpenStudy (anonymous):

oh, I see!

Thank you! :)
