It would be 7x-9 because 2x squared would be 4x, and you can only simplify two numbers if they have the same variable after it. So, all you can do is simplify this equation down to 7x-9.
Distance=(3/4) * (26 2/10 miles)
26 2/10 miles=26 1/5 miles=(5*26+1) / 5 miles=131/5 miles.
Therefore:
distance=(3/4) * (26 2/10 miles)=(3/4) * (131 /5 miles)=
=(131 *3) / (4*5) miles=393/20 miles= (19*20+13)20 miles=19 13/20 miles.
he has run 393/20 miles or 19 13/20 miles
