We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:
d = (1 +√2) × s
The inverse formula is:
s = d / <span>(1 +√2)
Plugging in numbers:
s = 7 (1 + </span>√2)
= 2.9 ft
Therefore the correct answer is A) <span>2.9 feet</span>
Answer: B. d - 0.2
Step-by-step explanation: 20%= 20/100= 0.2
Which means = d-0.2

vertex form of a parabola
y= a(x-h)^2 +k
y =a(x--3)^2 +2
y = a(x+3)^2 +2
Choice B
The minimum number of sides that a polygon must have is 3
-1+3m=2m+4
put the like terms together
3m-2m=4+1
m=5
