1/2(x+1)=2 which does a possible four-step process to find the solution of this equation

First you would distribute, 1/2 * x and 1/2 * 1. So you would end up with (1/2x+1/2)=2. Then you would subtract 1/2 from 2, and you would be left with (1/2x)=1 1/2. Then you would divide 1 1/2 by 1/2. You would then be left with x=3. The last step would be to plug in your answer and make sure it's correct.

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
