Solve the equation. dx 2 = dt Xe+9x Begin by separating the variables. Choose the correct answer below. 1 OA. dx= dt 2 9x xe 2 B. x dx=- dt +9x 2 c. xedx=dt OD. The equation is already separated. An implicit solution in the form F(t,x) = C is =C, where C is an arbitrary constant. (Type an expression using t and x as the variables.)
