Answer:
b
Step-by-step explanation:
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: 60 cm
Step-by-step explanation:
multiply sides together.
Answer:
2
Step-by-step explanation:
slope = difference of y/ difference of x
m = (9-5) / (4-2) = 4/2 = 2
3x-2-(2x+1)= 3x-2-2x-1
= x- 3
C. x - 3
