Description for Correct answer:
\( \Large x \circledast y = 3x + 2y \)

\( \Large \left(2 \circledast 3\right)= 3 \times 2 +2 \times 3 = 6 + 6 = 12 \)

\( \Large \left(3 \circledast 4\right) = 3 \times 3 + 2 \times 4 = 9 + 8 = 17 \)

Therefore, \( \Large \left(2 \circledast 3\right)+ \left(3 \circledast 4\right) = 12 + 17 = 29 \)
