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:
Order the list from least to greatest:
-12, -9, 0, 8, 15, 16, 17
subtract the least from the greatest: 17 - (-12)
17 + 12 = 29
The range is 29
