Answer: -18
<u>Explanation:</u>
Average rate of change is slope:
. Need to find the y-coordinates:
g(x) = -x² - 4x
g(6) = -(6)² - 4(6)
= -36 - 24
= -60
⇒ (6, -60)
g(8) = -(8)² - 4(8)
= -64 - 32
= -96
⇒ (8, -96)
m = 
= 
= -18
You can 14 rows of 5 chairs, which also means you can do 5 rows of 14. Or 7 rows of 10 or 10 rows of seven. That's all I'm getting that doesn't exceed the 20 row limit.
Answer:
1 17/40
Step-by-step explanation:
5/8+4/5
We need to get a common denominator of 40
5/6 * 5/5 = 25/40
4/5*8/8 =32/40
25/40 + 32/40 = 57/40
57/40 = 40/40 + 17/40 = 1 17/40
