Answer: f(x) = ∛(x+4)^2=8 + 3 = 11
4x5=20-9=11
Step-by-step explanation:
From top to bottom:
-20
-8
-2
4
10
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
The tree was 30 feet tall. If we divide 33 by 1.1(undoing the 10% increase) we get 30. We can prove this by multiplying 30 by 1.1
