Answer:
1) 2m + 3m2 - 4m=7
7) 3m2 – 2m + 4m= 11
8) 20 + 109 + 39 - 4= 164
3) 2m + 4m - 3m2= -3
9) 4xy + x + 2xy= 0
4) 2y + 14x - 7x + 9y= 18
10) 6m2 - 6m - 9m2= -51

Step-by-step explanation:
3 - 2x + 5 < -4(x + 2)
-2x + 8 < -4(x + 2)
-2x + 8 < -4x - 8
-2x + 8 + 4x < -8
2x + 8 < -8
2x < -8 - 8
2x < -16
x < -16/2
x < -8
Answer: A) x < -8
