It would be 10 ft.

You set up a right triangle with the base being 8 ft (the shadow), the height being 6 ft (his height) and you need the hypotenuse, a straight line from his actual head to his head in the shadow.

a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
take the square root of both sides
10 = c

Answer:

\frac{1}{(x-3)(x-2)}

Step-by-step explanation:

Factorise the denominators of both fractions

x² - 9 and x² - 4 are both differences of squares and factor as

x² - 9  = (x - 3)(x + 3) and x² - 4 = (x - 2)(x + 2), thus express as

\frac{x+2}{(x-3)(x+3)} × \frac{x+3}{(x-2)(x+2)}

Cancel the factors (x + 3) and (x + 2) from the numerators/denominators of both fractions leaving

\frac{1}{(x-3)(x-2)}
