Answer:

  1. x
  2. -1
  3. -2

Step-by-step explanation:

1.

[tex] \frac{ {x}^{2} + 8x }{x + 8} \\ \frac{x \times (x + 8)}{x + 8} \\ = x[/tex]

2.

[tex] \frac{3x - 2}{2 - 3x} \\ \frac{3x - 2}{ - (3x - 2)} \\ = - 1[/tex]

3.

[tex] \frac{10a - 2}{1 - 5a} \\ \frac{ - 2( - 5a + 1)}{1 - 5a} \\ = - 2[/tex]
