17. Solve -46x + 3) = -12(x + 10).<br>O A. X = 2<br>O B. x = -5<br>O C. x = 5<br>O D. X = 9​
SCORPION-xisa [38]

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.

= x(x(x+1) + 2(x+1))

=x(x+1)(x+2)
