18a+(a−9)2
Distribute:
=18a+a2+−18a+81
Combine Like Terms:
=18a+a2+−18a+81
=(a2)+(18a+−18a)+(81)
=a2+81

Answer:
4.2
Step-by-step explanation:
f varies inversly with L can be translated matimatically as:
● f = k/L
It takes 7 pounds of pressure to break a 3 feet long board.
Replace f by 7 and L by 3.
● 7 = k/3 => k=7×3=21

Let's find tge length of a board that takes 5 pounds of pressure to be broken.
● 5 = k/L
● 5 = 21/L
● L = 21/5 = 4.2
So the board is 4.2 feet long
