Answer: 91.65 ft
Step-by-step explanation:
(200*200) + (x) = 220*220
40000 + x = 48400
48400 - 40000 = x^2
8400 = x^2
91.65 = x
Answer:160 miles
Step-by-step explanation:
Since one inch is equal to 20 miles, multiply 8 by 20. 8*20 = 160
F(x)=8/x, g(x)=8/x
f(g(x)) = f(8/x)=8/<span>8/x=x,
</span>g(f(x)) =g(8/x) =8/<span>8/x=x,
so </span>f(g(x)) = g(f(x)) = x. if <span>f of x equals eight divided by x and g of x equals eight divided by x
