The answer would be -6 or letter B because
20 possibilities based on this as a combination not a permutation, 6 nCr 3 = 20
If $5,000,000 is invested at 4% interest compounded continuously, the investment will be worth $16,215,000 in 30 years.
300^2 + 500^2 = c^2
9000 + 250000=c^2
340000=c^2
sqrt (340000) = c
c = 583
300 + 500 + 583 = 1383
1380 is the perimeter
