Answer 1

Answer: I have no clue.

Step-by-step explanation: I Am in 7th grade.

Answer 2

`(F G H)(6) = (1891)/(7)`

Explanation:

Explanation:-

Given F(X)=7 x-1

G(X)=x²+1, and

H(X)=(x+ 1 /7)

(F G H)(6) = (F G ) H(6)

=
`F G ( 6 + (1)/(7) )` ( ∵ H(X)=(x+ 1 /7)

=
`F G ( (43)/(7) )`

=
`F( ((43)/(7))^(2) +1)` ( ∵ G(X)=x²+1)

=
`F(((43)^(2)+49 )/(49) )`

=
`F((1898)/(49) )` (∵ F(X)=7 x-1)

`= 7((1898)/(49) )-1`

`= ((1898)/(7) )-1`

`= (1898-7)/(7) = (1891)/(7)`

`(F G H)(6) = (1891)/(7)`
