Answer:

In this equation, the value of x is 9.

Step-by-step explanation:

-4(6x + 3) = -12(x + 10)

Distribute -4 to (6x + 3) and distribute -12 to (x + 10).

-24x - 12 = -12x - 120

Add 12x on both sides of the equation.

-12x - 12 = -120

Add 12 on both sides of the equation.

-12x = -108

Divide -12 on both sides of the equation.

x = 9

The value of x in this equation is 9.

Not sure. Please explain the steps.

Answer:

answer C

Step-by-step explanation:

hello

because this is not allowed to divide by 0 I would take x real different from 0 and from -5/4

$\dfrac{8x^3-10x^2-25x}{4x^2+5x}=\dfrac{x(8x^2-10x-25)}{x(4x+5)}=\\\dfrac{8x^2-10x-25}{4x+5}=\dfrac{(4x+5)(2x-5)}{4x+5}=2x-5$

indeed if we develop

$(4x+5)(2x-5)=8x^2-20x+10x-25=8x^2-10x-25$

hope this helps

do not hesitate if you have any question
