1.) -8 + 10(6 + 4r)
First multiply the 10 into (6 + 4r)
-8 + 60 + 40r
52 + 40r
2.) (8m² - 8m + 8) - (2m - 7m² - 6)
Distribute the - into (2m - 7m² - 6)
8m² - 8m + 8 - 2m + 7m² + 6
Combine like terms
15m² - 10m + 14
(idk if you need to factor this or if you can leave it as is)
Answer: ok fine

Answer:
$507.30
Step-by-step explanation:

-His investment amount is thus:

#We subtract to find how much more he would have if he started saving at 20;

Hence, Saul would have $507.30 more had he started saving 10 years earlier.
3.25 hours you take 4680÷1440 = 3.25
