Answer:

The answer is C. 16x² - 56xy + 49y²

Step-by-step explanation:

A perfect square trinomial is the result of a squared binomial, the perfect square trinomial would be a² + 2ab + b², as that is what you get when you expand the brackets.

Pls!! f(x)=√x+2 and g(x)=9x−4 f(g(x))= f(g(3))= show work pls thank uu

Answer:

Find $f(g(x))$ by substituting the entire g(x) function for x in f(x)

$f(x)=\sqrt{x} +2\\f(g(x))=\sqrt{(9x-4)} +2$ that's the answer
Then f(g(3)) is just putting in place of x in our new equation
$f(g(x))=\sqrt{(9x-4)} +2\\f(g(3))=\sqrt{(9(3)-4)} +2\\f(g(3))=\sqrt{(27-4)} +2\\f(g(3))=\sqrt{(23)} +2\\f(g(3))=6.80$ rounded to 2 decimal places
