Step-by-step explanation:

$x {}^{3} +9x {}^{2} +27x+27 \\ \\ {(3})^{3} + 9(3) {}^{2} + 27(3) + 27 \\ \\ 27 + 9(9) + 81 + 27 \\ \\ 27 + 81 + 81 + 27 \\ \\ = \: \: 216$

Answer 2

Answer:

x³ + 9x² + 27x + 27

No identity is used and there's no adding and subtraction so we will directly put x = 3

(3)³ + 9(3)² + 27(3) + 27

27 + 81 + 81 + 27

= 216 is the answer
