A canoe takes 4/t hours to travel upstream and (10-t)/(t plus2) hours to travel downstream,
\n" ); document.write( "What expression represents the total time it takes the canoe to travel both ways?
\n" ); document.write( "-----
\n" ); document.write( "(4/t)+(10-t)/(t+2)
\n" ); document.write( "---
\n" ); document.write( "least common denominator: t+2
\n" ); document.write( "----
\n" ); document.write( "= [(t+2)(4/t)+(10-t]/(t+2)
\n" ); document.write( "-------------
\n" ); document.write( "=[4+(8/t)+10-t]/(t+2)
\n" ); document.write( "----
\n" ); document.write( "= [4t + 8 + 10t-t^2]/(t(t+2))
\n" ); document.write( "----
\n" ); document.write( "= [-t^2+14t+8]/(t^2+2t)
\n" ); document.write( "----
\n" ); document.write( "= [-(t^2-14t-8)]/(t^2+2t)
\n" ); document.write( "-----
