let's recall that to find the inverse of any expression, we start off by doing a quick switcheroo on the variables, and then solve for "y".

Answer:
1. x = 2
2. x = 21
Step-by-step explanation:
Hope this helps
Since C = 2rπ
if the C of earth = 25000 miles
then the r = C ÷ (2π)
= 25,000 miles ÷ 2π
= 12500 ÷ π
≈ 3978.87358 miles
Since radius is a measure of the distance from the center to any point on the circle then that distance would be about 3978.8736 miles<span />
Option B i.e. Non-Euclidean
I'm going to refer to the length of the pool as L.
2x + 2L = perimeter.
The width of pool multiplied by two added to the length of the pool multiplied by two equals to the perimeter.
