Объяснение:

1)xy-7x+5y-35

2)x^2-5x-x-5=x^2-6x-5

3)6x^2+21x-10x-35=6x^2+11x-35

Answer 3

Let's simplify each of the given expressions one by one:

1. (x + 5)(y - 7) Expanding this expression using the distributive property, we get: xy - 7x + 5y - 35

2. (x - 1)(x + 5) Again, applying the distributive property, we have: x^2 + 5x - x - 5 Combining like terms, we get: x^2 + 4x - 5

3. (3x - 5)(2x + 7) Expanding using the distributive property, we get: 6x^2 + 21x - 10x - 35 Combining like terms, we have: 6x^2 + 11x - 35

Therefore, the simplified forms of the given expressions are:

1. xy - 7x + 5y - 35
2. x^2 + 4x - 5
3. 6x^2 + 11x - 35
