N³ - 2n² - 15n = 0
"n"
n (n² + 2n - 15) = 0
n = 0
n² + 2n - 15 = 0
Δ = (2)² - 4(1)(-15)
Δ = 4 + 60 = 64
n' = (-2+8) / 2 = 6/2 =3
n'' = (-2-8) / 2 = -10/2 = -5
Solution:
S {-5 , 0 , 3 }
Answer:
120 ft
Step-by-step explanation:
Represent the path length by P.
Then 0.55P = 66 ft, and
66 ft
P = ---------- = 120 ft
0.55
Answer:
6i
Step-by-step explanation:
Using the rule of radicals
× 
= 
and 
= i
Given
= 
= 
× ×
= 6 × i
= 6i
Answer:
x = 49
Step-by-step explanation:
The two interior angles added together equal the exterior angle.
Make an equation and solve for x.
x - 4 + 2x + 10 = 153
3x + 6 = 153
3x + 6 - 6 = 153 - 6
3x = 147
3x/3 = 147/3
x = 49
