Is x + 9 a factor of the polynomial P(x) = x^3 + 11x^2 + 15x -27? If so, write the polynomial as a product of two factors. If not, explain how you know.

Factored form of the polynomial will be (x + 9)(x² + 2x - 3).

   Given in the question,

Use synthetic division to find the other factor,

Since, (x + 9) is a factor,

(x + 9) = 0 ⇒ x = -9

So the divisor will be (-9).

-9 |     1     11       15      -27

          -    -9     -18        27

          1     2      -3         0

So the other factor will be (x² + 2x - 3).

       Therefore, factored form of the polynomial will be (x + 9)(x² + 2x - 3).

(x + 9) (x² + 2x - 3)

Yes, x+9 a factor of p(x)

Step-by-step explanation:

x³ + 11x² + 15x -27 = x² (x + 9) + (2x² + 15x -27)

= x² (x + 9) + (x + 9) (2x - 3)

= (x + 9) (x² + 2x - 3)

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
