Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>q is independent variable, we need to solve it for s:</u>
- 6q = 3s - 9
- 3s = 6q + 9
- s = 2q + 3
<u>Correct choice is </u>

Umm.. I have to see the problems, we might not have the same textbooks so
(s + 3t) * (2s - 2t) = 2s^2 - 2st + 6ts - 6t^2
