Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
Answer: 8.826, 8.85, 8.866, 8.9, 8.948, 8.97
Step-by-step explanation:
When simplifying you want to combine like terms so 14x²-12x² will equal 2x², now we move on to X, where 3x+11x will result in 14x, last we add up numbers without X so 4-3 is 1.
The Answer will end up being 2x²+14x+1 (B)
