Which of the following represents the zeros of f (x)=x^3-2x^2-6x+12
lianna [129]
F(x) = x^3 - 2x^2 - 6x + 12 = 0

lets try  substituting some of the factors of 12:-

f(2)  = 8 - 8 -12+12 = 0    So one  zero is x = 2 Answer

Dividing f(x) by (x - 2) we get:-

x^2 - 6   so the other 2 zeros are  sqrt6 and - sqrt6 or 2.45 and -2.45 to the nearest hundredth  Answer

Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1
Inessa05 [86]

Answer:

x^2/400 + x^2/625

(x-0)^2/400) +(y-0^2/625)

x^2=400

X=sqrt. 400

x = 20

y^2=625

y = sqrt. 625

y= 25

a^2-c^2=b^2

sqrt 400-625 = c

20-25=c

The correct answer is c=-5

(-5,0)

(5,0)

Which properties does not belong with the other three?
Oksi-84 [34.3K]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

x - 6 = 5

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

I am assuming that '3=x divided by 3' is supposed to be 3 = \frac{x}{3}.

⸻⸻⸻⸻

The first, second, and fourth equations have x divided by a number. To isolate x, we would have to use the multiplication property of equality.

⸻⸻⸻⸻

For the third one (x-6=5), the variable 'x' is being subtracted by 6. We would have to use the addition property of equality to isolate x.

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
