Answer:
Yes, it is.
Step-by-step explanation:
The second 8 in 8.8 is greater than the 0 in 8.01.
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
Answer:
- 2x² + 7x + 1
Step-by-step explanation:
f(x) - g(x)
= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1
= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms
= - 2x² + 7x + 1
If you are looking to round, then you simply either round up or round down due to the term before the place you want to round (in this case, the thousands place). when you round in this case, you would round down because 4 is less than 5 (the middle point between 0 and 10) in which case would give us 60,000
