Q. If r=2r = 2, what is r+2\sqrt{r + 2}?\newline____
  1. Plug in r=2r = 2: First, let's plug in r=2r = 2 into the expression. So we get 2+2\sqrt{2 + 2}.\newlineCalculation: 2+2\sqrt{2 + 2}
  2. Add numbers inside square root: Now, we add 22 and 22 together inside the square root.\newlineCalculation: 4\sqrt{4}
  3. Find square root of 44: Lastly, we find the square root of 44, which is 22.\newlineCalculation: 4=2\sqrt{4} = 2
