6) 12r + 3 + 5r - 5 7) 3 + 7x - 5 + 2x2 8) 5x + 4x2 + 10 + 2x2 + 2x – 6 + x – 1

Answer 1

Answer:

$1) \: - 22x + 9x \\ \\ = - 13$

$2) \: 15r - 7 - 16 \\ \\ = 15r - 23$

$3) \: n - 10 + 9n - 3 \\ \\ = 10n - 13$

$4) \: 12r + 3 + 5r - 5 \\ \\ = 17r - 2$

$5) \: 3 + 7x - 5 + 2 {x}^{2} \\ \\ = 2 {x}^{2} + 7x - 2$

hope this much helps uh ❣️

Answer 2

Answer:

The answers are..

Step-by-step explanation:

3) - 22x + 9x

= - 13x

4) 15r - 7 - 16

= 15r - 23

5) n - 10 + 9n - 3

= 10n - 13

6) 12r + 3 + 5r - 5

= 17r - 2

7) 3 + 7x - 5 + 2x²

= 2x² + 7x - 2

8) 5x + 4x² + 10 + 2x² + 2x - 6 + x - 1

= 6x² + 8x + 3
