$9,150,000,000,000,000,000$

the numbers should be

$9.15\times10^{18}$

$9.15E18$

because you move the point 18 places to obtain 9.15(the dot is initially at the end of the number)

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)
