Answer:
n = 15
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 3*(n-6)-(27)=0
Pull out like factors : 3n - 45 = 3 • (n - 15)
Then: 3 • (n - 15) = 0
It's pretty easy from there, good luck!
Answer:
2.5
Step-by-step explanation:
Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
I don't understand what you mean but this might be the answer
