2(2x + 3) = -6(x + 9)

sergeinik [125]

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

Multiply (2x+3) (-x -2)

Marysya12 [62]

Answer:

$-2x^{2} -7x-6$

Step-by-step explanation:

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

distribute first term, to the second term:

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

multiply:

$(-2x^{2})$ + (-4x) + (-3x) + (-6)

$-2x^{2} -4x-3x-6$

combine the like terms:

$-2x^{2}$ - 4x - 3x - 6

-7x

$-2x^{2}$ - 7x - 6

final answer :

$-2x^{2}$ - 7x - 6

hope this helped !!
