At what range distances from the fire's center is the temperature less than 280°C? Round your values to one decimal place?

In the vicinity of a bonfire the temperature T (in °C) at a distance of x meters from the center of the fire is given by

                                                        T(x)= 500,000/x2+400 

At what range distances from the fire's center is the temperature less than 280°C? (Assume x is positive. Round your values to one decimal place. Enter your answer using interval notation.)

    I will assume this: T(x)= 500,000/(x²+400)

    280= 500,000/(x²+400)

    x² + 400= 500,000/280

    37.2 m< x <37.2 m
