Answer:

Step-by-step explanation:
The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...
3x +12 < 0
x +4 < 0
x < -4 . . . . . makes the absolute value function change its argument's sign
Using this fact, we can divide the domain into intervals below -4, at -4, and above -4. The above answer shows the function value in each domain interval.
Answer:4x>2+3x+5
Step-by-step explanation:
12x>3+8x>2+9x>2+21x+10
12x>3+8x>2+9x>2+6x+15×10
4x^2(3x+2)+9x^2×6x
4x^2(3x+2)+3x(3x+2)+15x+10
4x^2(3x+2)3x(3x+2)+5(3x+2)
Cancel
3x+2(4×^2+3x+5)
