See, pls, the offered decision:
1. this ratio has another form: 2x/3x/4x;
2. the difference between the largest and the smallest is 4x-2x=10.
Then x=5, and the sequence of numbers is 10/15/20, where 15 is the middle number.
Answer: 15.
V = (4/3)×3.14×(1.5^3)
V = 14.1 in^3
(5x-12)^2
Square factor of 25 is 5.
Square factor of 144 is 12.
Hope this helps. I didn't understand what to do with it.
