C=2*pi*r or c=pi*d
c=7.6*pi
c=23.88
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
Hello from MrBillDoesMath!
Answer: It is part of an arithmetic progression
Discussion:
143 - 125 = 18
125 - 107 = 18
107 - 89 = 18
The value 18 is subtracted from each term in the arithmetic sequence.

Answer:
64
Step-by-step explanation:
The interior angle of a circle has the theorem divide in 2 the sum of the arcs on the circle.
The circle has arcs 42 and 86.
The interior angle is 42 + 86 = 128.
128/2 = 64
