I think the answer is B but i could be wrong
Answer:
a^3 + b^3
Step-by-step explanation:
(a + b)(a^2-ab+b^2)
a(a^2 -ab +b^2) +b(a^2-ab+b^2)
a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3
a^3 -a^2b +a^2b ab^2-ab^2 + b^3
The final answer will then be:
a^3 + b^3
Hope this helps! Have a great one! And I give out the best of luck for whatever quiz this is on!

Answer:
Step-by-step explanation:
Set up a ratio in the form of pages/minute:
then fill in next to that how many pages per minute George can read:
Now we want to figure out how long (time is our unknown, so we call that x) it will take him to read 85 pages. The 85 goes in a ratio on the same line as the other number of pages:
Cross multiply to get 15x = 1020
Now divide both sides by 15 to get x = 68 minutes, which is an hour and 8 minutes.
