For another question, Nancy needs her to mark the numbers 1 1/3 and -1 1/3 on the number line. How many spaces does she need between 1 and 2, and between -1 and -2, so that she can mark 1 1/3 and -1 1/3 ? PLS! HELP!!

  3 each

Step-by-step explanation:

Nancy is planning to mark numbers that have fractions with a denominator of 3, so she needs 3 spaces between the integer values.

The denominator tells you the number of equal parts that each unit is divided into.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i found two solutions,   n = 2 • ± √3 = ± 3.4641
