Answer:
2w^2 -7w-2
Step-by-step explanation:
(4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Distribute the minus sign
(4w^2 – 4w – 8) – 2w^2 - 3w + 6
I like to line them up vertically
4w^2 – 4w – 8
– 2w^2 - 3w + 6
-----------------------------
2w^2 -7w-2
The formula for strontium phosphide is Sr3(PO4)2.
Hopefully this helps! :)
Answer: The variables have a weak positive correlation
