Answer:
8 +3i
Step-by-step explanation:
(9 + 6i) − (1 + 3i)
Distribute the minus sign
(9 + 6i) − 1 - 3i
Combine like terms

Answer:
The latitude of a place is its distance north or south of the equator.
Step-by-step explanation:
-3x² + 2y² + 5xy -2y + 5x² - 3y²
= -3x² + 5x² +2y² -3y² + 5xy -2y
= 2x² - y² +5xy -2y

Answer:
111.58 feet
Step-by-step explanation:
Given that the length of the string (AB in the attached diagram) is 120 feet.
Selena (at point D) is standing 24 feet from point A, where the kite is attached to the ground.
Since the kite is directly above Selena's head, the problem forms a right triangle.
Using Pythagoras theorem

Serena's height (CD=6 feet)
The distance of the kite above her head is BC in the drawn diagram.
Therefore:
|BD|=|BC|+|CD|
117.58=|BC|+6
|BC|=117.58-6
|BC|=111.58 feet
The kite is approximately 111.58 feet above Selena's head/
25,386 to the nearest 1000 is 25,000. This is because 386 is less than 500, and it’s only when a number is over or equal to 500 that you round up to the next thousand.
