A= 3.14* 12^2
= 3.14* 144
= 452.16cm^2
Answer: the answer is 27.1 km
Step-by-step explanation:
3/2 is the answer
i say this because you have to think of the problem as
4y=6x
divide the 4
y=6x/4
simplify
3/2
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
