Since 40 acres of land produces 600 bushels
so the bushels produced by 1 acres of land is 600/40=15
So bushels produced by 75 actes of land = 75×15=1125 bushels
<h3>
Answer: x^2 + 6</h3>
Work Shown:
(f o g)(x) = f(g(x))
f(x) = x + 7
f( g(x) ) = g(x) + 7 ... replace every x with g(x)
f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1
f( g(x) ) = x^2 + 6
(f o g)(x) = x^2 + 6
