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>
The answer is 20 I believe
<span>-6x - 2 = 40
-6x = 42
x = -7

4,500 mass. if you multiply 0.45 and 10,000 you'll get 4,500
The answer is B, rational numbers :)
