Answer:

Answer:
B
Step-by-step explanation:
To do this, you need to complete the square.

Therefore, the correct answer is choice B. Hope this helps!
X+6≤12+2x
x-2x≤12-6
-x≤6
-x/-1≤6/-1
because we divide by a negative number, we have to flip the sign of inequality.
x≥-6
Answer: x≥-6
(3x - 2)²
= (3x - 2) (3x - 2) use distributive property or FOIL
= 3x(3x) + 3x(-2) - 2(3x) - 2(-2)
= 9x² - 6x - 6x + 4 combine like terms
= 9x² - 12x + 4
