Answer:
5/11
Step-by-step explanation:
5 blue marbles and 11 total marbles
31.68 is 45% of 70.4
n * 0.45 = 31.68
divide both sides bu 0.45
n=70.4
The correct answer is: -18 .
________________________________________
9i * 2i = 18 i² .
________________________________________
" i " is an imaginary number equal to "√(-1) " .
" i² " = [√(-1)] ² = √(-1) * √(-1) = -1 .
________________________________________
18 * i² = 18 * -1 = -18 .

The number that is the least or furthest is 21 because they are all positive and so that makes the littles number the least, but if they where all negatives it would be the greatest negative.
