You just have to add the base numbers together and thats your answer.
Answer:
the scatter plots shows a positive association.
(1 - 3i)(5 + 5i)(4 - 1i)
= (5 + 5i - 15i - 15i²)(4 - 1i)
= (5 - 10i - 15i²)(4 - 1i)
= 20 - 40i - 60i² - 5i + 10i² + 15i³
= 20 - 45i - 50i² + 15i³
Because the lines are parallel two x angles are 27 and angles in a triangle = 180 so double 27 to get 54, then 180-54= 126 so t should be 126 degrees, but if not sorry
This is false
You need to find the surface area
