Answer:
The third one is right.
Step-by-step explanation:
#1 is 2 X 10 to the 4th power
#2 is America because America has 20,000 a year and UK has 10,000 a year. The difference between them is 10,000 kilograms a year
Let's rewrite the given expression correctly:
(2y3 + 3y2 - 4y - 5) / (y + 1)
Dividing the expression between y + 1 we have:
2y2 + y - 5
We can check the result:
(2y2 + y - 5) * (y + 1)
= (2y3 + y2 - 5y + 2y2 + y - 5)
= (2y3 + 3y2 - 4y - 5)
Division OK.
Answer:
The result of the division is:
2y2 + y - 5
