<span>g(x) = x^3 - 9x^2 + 2x + 48 ?
Probe some roots. When you use x = - 2
you will have: (-2)^3 - 9(-2)^2 + 2(-2) + 48 = -8 - 36 - 4 + 48 = 0
So, - 2 is a root
From that you can divide x^3 - 9x^2 + 2x + 48 by x + 2 and you will get
x^2 - 11x + 24
Then you can factor that: (x - 8)(x - 3)
So, the three roots are x = - 2, x = 3 and x = 8, which is the option B.
Answer: option B. x = 8, x = -2 , and x = 3

Answer:
yes this is true
Step-by-step explanation:
this is because 2x3=6 so 2x3g=6g
Answer:
1:1
Step-by-step explanation:
The ratio would be 1:1 since it's a square, the sides will always be the same. In a square ,all sides are the same length. If they are not, then it wouldn't be a square.
Answer:
x=31
Step-by-step explanation:
4+ sqrt (x+5) = 10
Subtract 4 from each side
4 -4+ sqrt (x+5) = 10-4
sqrt(x+5) = 6
Square each side
(sqrt(x+5))^2 = 6^2
x+5 = 36
Subtract 5 from each side
x+5-5 = 36-5
x = 31
