Can someone plz explain this to me:

First ,find the unit fraction.

Next ,divide the fraction by the unit fraction to get a whole number

Example-4/5

The unit fraction is 1/5 since the denominator is 5.

4/5 divided by 1/5 is 4

So ,4 1/5 would be the answer!

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
