a^2+b^2=c^2 (13+3b)^2+b^2=(14+3b)^2 9b^2+78b+169+b^2=9b^2+84b+196 10b^2+78b+169=9b^2+84b+196 minus 9b^2 both sides b^2+78b+169=84b+196 minus 84b both sides b^2-6b+169=196 minus 196 both sides b^2-6b-27=0 factor (b+3)(b-9)=0 set to zero b+3=0 b=-3, false, dimentions cannot be negative
5,555 can be rounded up to 6,000 because the 5 next to the five thousand will make it go up. while the 4,444 will round to 4,000 . I don't have a clear answer but I hope this helps.
