Answer:
Same
Step-by-step explanation:
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

0, -5, and 3
because </span><span>f(x) = 9x3 + 18 x2 - 135x =x (x+5)(x-3)</span>
Number 8:
m1 = 120°
m2 = 60°
m3 = 120°
m4 = 60°
m5 = 60°
Number 9:
m1 = 100°
m2 = 70°
79.99-12%=70.39
70.39*12%= 4.75
70.39+4.75=$75.14
