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

A student makes and sells designer T-shirts to earn extra cash. The material needed to make each T-shirt costs $4.25. Currently,
natita [175]

Step-by-step explanation:

Let x be the number of designer T shirts.

To break even,

Total Cost = Total Sales

Fixed Cost + Variable Cost = Total Sales

given the promotional advertising is classified under fixed cost,

500 + 4.25x = 15x  \\ 15x = 500 + 4.25x \\ 15x - 4.25x = 500 \\ 10.75x = 500 \\ x = 500 \div 10.75 \\  = 46.5 \\  = 47 \: (round \: off \: to \: nearest \: whole \: number)
