Answer:
<em>k = 0</em>
Step-by-step explanation:
-8k = 8k
Add 8k to both sides.
0 = 16k
Divide both sides by 16.
0 = k
k = 0
1. 437,003,000,000
2. 53,250,000
3. 797,619,000,323
4. 11,006,007
5. 84,000,037,800
Any multiples of 4.5:1.5 would work because being proportional just depends on whether you can reduce to get the same answer of the first triangle. You could do anything like 9m and 3m or 27m and 9m
