Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2

r=x
r=

Area=

r^2
so..
A=

(

)^2
=

(

)
=

(38-x) is perimeter
then

(

)^2

+ (

)^2
then you graph it and it equals
16.716 cm the circumference of the circle
Answer:
<em>b = 5</em>
Step-by-step explanation:
If you do the long division you'll see that it is x - 2.
To stretch it vertically, you'll need a coefficient greater than 1 in front of the x. If you want to flip the graph over the x axis that coefficient needs to be negative. So it can only be D
