Okay, so we want to find G composed evaluated at six. So it's there for berating this. Now. We'll start by evaluating F evaluated at six. That's D, and then we get six squared sport was six. Squared is 36 plus four. They're not people supporting. Do we have G evaluated that 40? So what's that? You have always about 40. That's two times 40 plus three, which is equal to 80. Those three. That gives us a 83.
