−4 = √s + 8 − s anyone

OpenStudy (anonymous):

do you want an explanation or a solution?

OpenStudy (anonymous):

solution aka the answer

OpenStudy (anonymous):

s=16

OpenStudy (anonymous):

i put that and got it wrong!

OpenStudy (anonymous):

Just to be sure, it is only sqrt s not sqrt(s+8)

OpenStudy (anonymous):

16 works.

OpenStudy (anonymous):

-4 = √16 + 8 - 16

OpenStudy (anonymous):

-4=4+8-16

OpenStudy (anonymous):

-4=-4

OpenStudy (anonymous):

That means 16 does work. You must have plugged it in wrong

OpenStudy (anonymous):

no 16 is wrong

OpenStudy (anonymous):

see!

OpenStudy (anonymous):

It is because 8 is under the radical. I did not know that

OpenStudy (anonymous):

s=8 now because it is under the radical

OpenStudy (anonymous):

sorry thats my fault thank you!
