Hello! And thank you for your question!

First you are going to find the GCF:

GCF = r

Then factor out the GCF:

r (3r^2 over r + 7r over r)

Then simplify what is in the parentheses:

r(3r + 7)

Final Answer:

r(3r + 7)

One root of f(x)=x^3-9x^2+26x-24 is x = 2. What are all the roots of the function? Use the Remainder Theorem.

aniked [119]

Answer:

$x=3$ or $x=4$

Step-by-step explanation:

the given function is;

$f(x)=x^3-9x^2+26x-24$

According to the rational roots theorem, the possible rational roots are;

$\pm1,\pm2\pm3,\pm4,\pm6,\pm8,\pm12,\24$ .

According to the Remainder Theorem, if $f(a)=0$ , then $x=a$ is a zero of the polynomial.

$f(3)=3^3-9(3)^2+26(3)-24$

$f(3)=27-81+78-24$

$f(3)=24-24=0$

Also,

$f(4)=4^3-9(4)^2+26(4)-24$

$f(4)=64-144+104-24$

$f(4)=64-64=0$

Therefore the other roots are;

$x=3,x=4$

Decide if the following scenario involves a permutation or combination. Then find the number of possibilities. The student body

Troyanec [42]

Answer:

735,130.

Step-by-step explanation:

The order of election of the 3 representatives does not matter so it is a combination.

The number of possible combinations

= 165! / 162! 3!

= (165 * 164 * 163) / (3*2*1)

= 735,130.
