Answer:
f(-2) = 0
f(1) = 12
(x^3 - 7x - 6) / (x + 2) = x^2 - 2·x - 3 = (x - 3)(x + 1)
x^3 - 7x - 6 = (x + 2)(x - 3)(x + 1)
28ft because you would have to find the perimeter
Set up the following equation for this segment:
x is segment AB's length, and 3x is segment BC's length. 20 is segment AC's length.
Combine like terms:
Divide both sides by 4 to get x by itself:
x will equal 5.
Plug this value into the values for both segments:
Segment AB:
Segment AB is 5 inches long.
Segment BC:
Segment BC is 15 inches long.
Andrew can reach a maximum of 
high up the wall.
The right-angled triangle formed can be solved using the 
ratio. that is
where 
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for , we get
Since Andrew can reach an extra 
above the point where the ladder rests against the wall, the maximum height Andrew can paint is
