Which of the following represents the zeros of the function
umka21 [38]
<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

Can someone help me with this question?
meriva

Answer:

m = 4

Step-by-step explanation:

\because ABCD\sim QRST

\therefore \frac{10}{m}= \frac{15}{6}

\therefore m= \frac{10\times 6}{15}

\therefore m= \frac{60}{15}

\therefore m=4

Use synthetic division to find the expression for the area of the base of a rectangular prism with height x 4 and volume x3 2x2
IRINA_888 [86]

The expression for the area of the base of Prism is   x2 – 2x – 9

The volume of a rectangular prism is this

Volume = Area x Height

Substituting the given expressions

x3 + 2x2 - 17x - 36 = Area x (x + 4)

Area = (x3 + 2x2 - 17x - 36) / (x + 4)

Now, let's use synthetic division

-4 |    1    2    -17   -36

----    __-4___8___36

        1    -2     -9     0

The expression for the area is

Area = x2 - 2x - 9
