Answer:
The correct answer is A) 3x(3x + 2)(3x - 2)
Step-by-step explanation:
In order to find this, first take out the greatest common factor.
27x^3 - 12x
3x(9x^2 - 4)
Now, what is left in parenthesis is the difference of perfect squares. This allows us to factor.
3x(3x + 2)(3x - 2)
Answer:
J) -4.5
Step-by-step explanation:
-12x=54
x=54÷(-12)
x=-4.5
