(f∘g)(3) = f(g(3))
Find g(3) by substituting x=3 in g(x)
g(x)=x²-1
g(3)=3²-1
g(3)=9-1
g(3)=8
f*g(3) = f(g(3)) = f(8)
find f(8) by substituting x=8 in f(x):
f(x)=2x+3
f(8)=2(8)+3
f(8)=16+3
f(8)=19
So f∘g(3) = 19
Sorry I am wrong
Answer:
Just look it up. I checked and it shows all the correct answers.
Step-by-step explanation:
Hello There!
Area = l x w
14 =

Multiples of 14:
1 and 14
7 and 2
7 and 2 are the only ones with a difference of 5.
Therefore, the length is 7ft and the width is 2ft.
Hope This Helps You!Good Luck :)
