Answer:
-12s^2 + 11st - 2t^2.
Step-by-step explanation:
(-3s + 2t)(4s - t)
= -3s(4s - t) + 2t(4s - t)
= -12s^2 + 3st + 8st - 2t^2
= -12s^2 + 11st - 2t^2.
Note: When I use the double equal sign, I mean the triple bar used with modular arithmetic
10^3 = 1000 == -1 (mod 1001)
10^3 == -1 (mod 1001)
(10^3)^672 == (-1)^672 (mod 1001)
(10^(3*672) == 1 (mod 1001)
10^2016 == 1 (mod 1001)
10*10^2016 == 10*1 (mod 1001)
10^2017 == 10 (mod 1001)
Final Answer: 10
57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20
------ -------
2 2
x = -10

In the picture, I hope that it's a clear solution.
