Step-by-step explanation:
![\displaystyle [3 + i]^2 = [3 + i][3 + i] = 9 + 6i + i^2 → 9 + 6i - 1 → 6i + 8](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B3%20%2B%20i%5D%5E2%20%3D%20%5B3%20%2B%20i%5D%5B3%20%2B%20i%5D%20%3D%209%20%2B%206i%20%2B%20i%5E2%20%E2%86%92%209%20%2B%206i%20-%201%20%E2%86%92%206i%20%2B%208)
Therefore, the d-value is 6.

Answer:
the two would 20 miles apart on a coordinate grid .
Step-by-step explanation:
if you look at a 60 by 60 coordinate grid (40,-30) is 20 spaces away from (-60,-30).
Unfortunately you have not included the directions. Are you supposed to solve for x? or for y?
Suppose the directions say, "Solve for x." Then, clear out the decimal fraction by mult. both sides of the given equation by 10. This will give you the solution, that is, a formula for x in terms of y.
