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)
It would take you 26.1 minutes to clean all the showers. If it takes 5.22 minutes to clean the one and you have five to clean just multiply the time by five. Good luck!
Answer:
You must show us the statements that are given. This question can not be answered without that information. Have a nice day!!! :-)
Step-by-step explanation:
The prefix 'kilo' stands for 'one thousand'. So, 1 km = 1000m
This obviously implies that 8km is the same as 8000m
