Start with the original expression.
Use the Distributive Property — multiply 
by both 
and 
.
Combine the like terms — add up all the constants.
Reorder the terms.
9+3=12
30+20=50
300+100=400
Then add.
12+50+400=462
<span>So 339+123=462</span>
Answer:
2.75
Step-by-step explanation:
The amplitude is half of the difference between the highest and lowest y-coordinates.
amplitude = 0.5|6.75 - 1.25| = 0.5(5.5) = 2.75
