Answer:

(-∞,-9) U (2,3)

Step-by-step explanation:

(x+9)(x²-5x+6) < 0

x²-5x +6

= x² -3x -2x +6

= x( x-3) -2(x-3)

= (x-3)(x-2)

Substituting

(x+9)(x-2)(x-3)

For x < -9

the term is negative

For x >-9 x<2

the term is positive

For x>2 x<3

the term is negative

For x>3

the term is positive

(x+9)(x-2)(x-3) < 0

(-∞,-9) U (2,3)

Use the distributive property to remove the parentheses. -6(11 - 2)

salantis [7]

Answer:

-66+12 or -54

Step-by-step explanation:

To remove the parenthesis multiply the number outside of the parenthesis (in this case -6) to the numbers inside of the parenthesis (11, and -2).

$-6*11=-66$

A negative multiplied by a positive is a negative.

$-6*-2=12$

A negative multiplied by a negative is a positive.

$-66+12=-54$
