Answer 1

the person above me is correct but he really does not give u all the answers so i got it

Explanation:

1) 3

2) 2

3) 2

4) (t + 2) (t + 8)

5) (n - 7) ( n - 8)

6) (q - 6) (q - 2)

7) 6

8) (w - 8) ( w + 1)

9) (r + 10s) ( r + 9s)

10) (m + 4n) (m - 7n)

11) p= -4, q= -7

12) p = -3, q = 7

now for gaca students ik the teach will move the answers around so thats why i just have u the answer Thank you and have a great day!
