The answer x = -3 is correct ; not really any mistakes made but they do seem to skip a step from 8^(-1) to 2^(-3) if that is confusing you.

8 = 2^(3)
so
(8)^(-1) = (2^3)^(-1) = 2^(3*-1) = 2^(-3)

The two circles shown above have radii of 8 in. and 2 in.

algol [13]

Answer:

1/4

Step-by-step explanation:

For the first circle 2 x 2in = 4 to find diameter

4 x 3.14 = 12.56

6in x 2 = 12

12 x 3.14 = 37.68

simplify

12.56/37.68

6.28/18.84

3.14/9.42

So the answer is 1/4 since 3.14 x 2 = 6.28

Also since the radius is 2 times longer
