What is the solution of the quadratic inequality x2 − 2x − 3 < 0? (∞, -2) υ (3, ∞) (∞, -1] υ [3, ∞) (-1, 3) [-2, 3]

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

192/15 = 12.8.
