Because your question isn't specific or formatted exactly, I cannot guarantee that my answer is what you expect.
  
√2x - 1 + 2 = 5
  √(2x + 1)² = 5²
        2x + 1 = 25
              2x = 24
              /2      /2
                 x = 12

Therefore x = 12.
Proof:

    √2x - 1 + 2 = 5
√2(12) - 1 + 2 = 5
    √24 - 1 + 2 = 5
                √25 = 5
                    5 = 5

Daltons dad rode 1 kilometer north 2 kilometers west 1 kilometer south and 2 kilometers east. Dalton rode the same path 5 times
Fynjy0 [20]

Answer:

Dalton didn't ride any kilometer farther since he keeps threading in the same path as that of his father.

Step-by-step explanation:

If Dalton's dad rode 1 kilometer north, 2 kilometers west 1 kilometer south and 2 kilometers east, then he has been moving in a rectangular path.

If Dalton rode in the same path 5times, then Dalton's has not move farther than his dad since he is still moving in the same rectangular path. He is only expending more energy.

Their final destination will still be the same for both of them no matter how many times Dalton keeps threading in the same path.
