This may not be correct but Georgia will be about nine if u subtract 6 from 15... And as for Jerry, if he swims for 4 hours, at 2 miles, he might be swimming 480 miles.. 2x60 (aka and hour x 2) 120.. Do that 4 times and u end up with about 480.. So sorry if I'm wrong
He would need 6 meters of copper piping or just a tiny tincy bit more
The only way the expression can be factored is if a -3 is pulled out...
-3(5t+2)
