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:
I believe the answer is (-7.4) Not really great at math either
Step-by-step explanation:
Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side
