Answer:
D.) 4, 5, 8.

Explanation:
By the rules of supplementary and complementary angles, we know that angles directly across from one another are congruent. And since we know that lines 1 and 2 are parallel, the same angles on those lines would be congruent as well.
This means that 1 is congruent to 4, as it is congruent to 5, as well as 8.

Answer:

$\boxed{- 12 {s}^{2} + 11st - 2 {t}^{2} }$

Step-by-step explanation:

$= > ( - 3s + 2t)(4s - t) \\ \\ = > - 3s(4s - t) + 2t(4s - t) \\ \\ = > ( ( - 3s) \times 4s )- (( - 3s) \times t) + (2t \times 4s) - (2t \times t) \\ \\ = > - 12 {s}^{2} - ( - 3st) + 8st - 2 {t}^{2} \\ \\ = > -12 {s}^{2} + 3st + 8st - 2 {t}^{2} \\ \\ = > - 12 {s}^{2} + 11st - 2 {t}^{2}$
