Напимать незнаю какие

Answer 2

5 + 5 + 5 + 5 = 20, not 30.

To solve the equation 357 × (285 + 851) = 357 × 285 + x × 851, we need to find the value of x that makes the equation correct.

Let's solve it step by step:

1. First, calculate the value of 357 × (285 + 851): - 357 × (285 + 851) = 357 × 1136 = 405,552.

2. Next, calculate the value of 357 × 285: - 357 × 285 = 101,745.

3. Now, we have the equation: 405,552 = 101,745 + x × 851.

To find the value of x, we need to isolate it on one side of the equation. Let's do that:

4. Subtract 101,745 from both sides of the equation: - 405,552 - 101,745 = x × 851. - 303,807 = x × 851.

5. Divide both sides of the equation by 851 to solve for x: - x = 303,807 / 851. - x ≈ 357.5.

Therefore, to make the equation 357 × (285 + 851) = 357 × 285 + x × 851 correct, the value of x should be approximately 357.5.

Please note that the value of x is an approximation since we rounded the result.
