The answer is
f(x) = 9x3 + 18 x2 - 135x can be written as f(x) = x( 9x2+ 18 x - 135)
the first zero must be = 0
let's find the another zeros by solving 9x2+ 18 x - 135=0
f(-5)=135-135=0, so the answer is
<span>
0, -5, and 3
because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>

Answer:
A = 400 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the vertical height ) , then
A = × 20 × 40 = 10 × 40 = 400 ft²
