Answer:
120π
Step-by-step explanation:
diameter = 120
radius = 60
Cirumference= 2πr
2 x π x 60 = 120π
P=1500x.8+100
1500x.8=1200
1200+100=1300
Answer=1300
Recall the double angle identity:

Then

Plug in the values for x and y to check.
-6>8-10
-6>-2
Final answer: False
This is because -6<-2. Remember that for negative numbers, the number with the greater absolute value is less.
4n^4 √3n I believe would be the simplified form.
