A. 3^n 3^20
b.N^n N^20
c.12^n 12^9
d.237^n 237^4
1/4(6 + 2c) > 3
0.25 (6+ 2c) > 3
1.5 + 0.5c > 3
0.5c > 1.5
c > 3
Or multiply both sides by 4 to get rid of the 1/4,
6 + 2c > 12
2c > 6
c >3
Answer:
2
Step-by-step explanation:
the only positive variable after the problem is solved is 2
-4m+20 = -12
-4m = -32
m = 8
