Which expression represents the composition (gof) (x) for the functions below f(x)=3x-2 g(x)=1+2x

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

so u can mark brainlist

the answer is b because it has ^2 and the rest do not.
