idk what to do with this?

Do we just have to find the time in this question?
And is any other equation given? :)

that's all nothing else is need right now.

could i show you what i have and maybe you can help from there?

|dw:1397796459525:dw|

|dw:1397796552699:dw|

\[t=\frac{ 53+\sqrt{105} }{ 8 }, t=\frac{ 53-\sqrt{105} }{ 8 }\]

Yes, if you got that by calculating the above equation, then yes. :)

yay!

can we do one more?

Sure!

okay thanks.

\[r=7*t^2-51*t+92\]

for this one i thought using quadratic formula right of hand would be a good idea

|dw:1397798167883:dw|

|dw:1397798377673:dw|

thanks for the help

:)
