41-x=2x-1

x=14
41-14 is 27

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(-2, 5)

Point B(5, 5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(5--2)^2+(5-5)^2}$
(Parenthesis) Simplify: $\displaystyle d = \sqrt{(5+2)^2+(5-5)^2}$
(Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(7)^2+(0)^2}$
[√Radical] Exponent: $\displaystyle d = \sqrt{(7)^2}$
[√Radical] Evaluate: $\displaystyle d = 7$

If you use the real Pi , 3.140625 , from a real ratio 201 /64 , you would get 37.6875 inches . All ruler measurements like 1/2 , 1/4, 1/8 ,1/16 … is where the last decimal integer ends in 5 , just like the real Pi . If you use the present day Pi , your decimal integer circumference length keeps getting ever smaller , 10 , 100 , 1000 … in this case you would have a shrinking diameter . You are better off using the real Pi, that i have proven with Quora. Richard Eicholtz
