Answer:
2 (n + 2) = 2n + 4
n + n + n + n = 4n
2 (3n) = 6n
4n + n = 5n
Step-by-step explanation:
Circumference of a circle=diameter times pi
50.24=d(3.14)
d=16
radius is half of diameter so radius is 8
Area of a circle=pi(r^2)
(3.14)(8^2)=(3.14)(64)=200.96
Subtract C in both sides:
2c + 1 = 1
Subtract 1 on both sides
2c = 0
The solution is:
x = 0

If you don't know the value of 'a', we can only simplify.
4a - 11a = -7a
We combine since they are like terms.
