(can somebody find the sum of this)

(5+2i)+(8-3i)

she will travel a distance in the range of 3 - 11 miles

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
