Answer:
79% decrease
Step-by-step explanation:
Subtract 6400-1344=5056
Find percent decrease (5056/6400)x100=79
79% decrease is our final answer
13 because decimal is 4 or below let it rest or 5 or more go up one more
Distance formula: SR (A^2+B^2)
SR [(2+9i)^2 + (2-4i)^2] =
SR [4 + 18i + 81i^2 + 4 - 8i + 16i^2] =
SR [8 + 10i + 97i^2]
