This is a difference of perfect squares which is of the form:

(a^2-b^2)

And which always factors to:

(a-b)(a+b)

In this case:

(5x-8)(5x+8)

A car is driving northwest at vv mph across a sloping plain whose height, in feet above sea level, at a point nn miles north and

solong [7]

Northwest is 45 degrees north of west. If a car travels a distance x miles northwest, its northerly component gains x/sqrt(2) miles and its easterly component LOSES xsqrt(2)/ miles.

Resultant height is h = 4500 + 100x/sqrt(2) - 75x/sqrt(2) = [25/sqrt(2)]x + 4500
dh/dt = [25/sqrt(2)]dx/dt = [25/sqrt(2)]v
