$\bf \begin{cases} f(x)=2x+3\\ g(x)=x^2+1 \end{cases}\qquad \qquad g(3)=(3)^2+1\implies g(3)=\boxed{10} \\\\\\ f(~~g(3)~~)\implies f\left( ~~\boxed{10}~~ \right)=2(10)+3\implies \stackrel{f(g(3))}{f(10)}=23$

Which statement is best represented by the inequality d>11?

ankoles [38]

For this case we have the following inequality: $d> 11$

So, the correct option is:

Mo worked more than 11 hours this week.
