-x(3x-10)=8
-3x^2+10x=8 (DISTRIBUTE)
-3x^2+10x-8=0 (BALANCE TO ZERO)
(-3x+4)(x-2)=0 (FACTOR)
(-x+4/3)(x-2)=0 (SIMPLIFY)
{x=2 OR x= 4/3}
In 144 minutes, or at 5:19 pm, the trains will arrive at the same time again.
The answer if I am correct should be C. 6, since if you divide forty-eight by two you get twenty-four. Twenty-four divided by four equals six, and twenty-four divided by three equals eight, eight is the number that would be the remaining amount of days. Hope this helps you and have an amazing day!
