1/n^2 and n^-2 are the same, and 16 and 1/16 definitely aren’t the same 4^-2 is just -4 * -4, and because negative * negative = positive, that adds up to being 16.

The answer is 1/16.

What is the justification for each step in the solution of the equation?
otez555 [7]

23x-13=2(x+2)

First you would distribute the 2 into the parenthesis

It will look like this after: 23x-13=2x+4

Then you would subtract 2x on both sides because u have to get the x's on one side

It will look like this after:21x-13=4

Then you would add 13 to both sides

It will look like this after: 21x=17

Then you would divide 21 on both sides

Your final product is 21/17

In a circle, the arc is two times the length of the angle.

EFG = 98°

98 x 2 = 196

Minor arc EG = 196°

Hopefully this helps :)
