Answer:

3 ( x - 3) ( x + 1)

Step-by-step explanation:

I believe the question is

-6x² + 15x + 9

Multiply -6 by 9 = -54

To factorise you find the factor of -54 that will add up to +15.

The factors = 18 & -3.

Rewrite equation by replacing the 15x by the factors.

-6x² + 18x - 3x + 9

Factorise

-6x(x - 3) -3 ( x - 3 )

(x - 3) ( -6x - 3)

(x - 3) -3( x + 1)

-3 ( x - 3) ( x + 1)

WARRIOR [948]

Answer:

D. $512,000

Step-by-step explanation:

Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation $2000(2^{8})$ . $2^8$ can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!
