9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>

Step-by-step explanation:
Answer:
the amplitude of the function is 2.5
6x - 10(x + 12) = -4x - 24
<em><u>Distributive property.</u></em>
6x - 10x - 120 = -4x - 24
<em><u>Add 10x to both sides.</u></em>
6x - 120 = 6x - 24
<em><u>Cancel like terms.</u></em>
<em>Add 24 to both sides.</em>
-96 ≠ 0.
This equation is incorrect, as -96 will never be equal to 0.
