Zack can use what he knows about multiplication to find the answer to \(4 \times 9\). He can break it down as follows:
Since \(4 \times 9\) can be expressed as \(3 \times 9 + 1 \times 9\), Zack can calculate:
\[
4 \times 9 = (3 \times 9) + (1 \times 9)
\]
We know that \(3 \times 9 = 27\). Also, \(1 \times 9 = 9\).
So, Zack can add those two results together:
\[
4 \times 9 = 27 + 9 = 36
\]
Thus, the answer to \(4 \times 9\) is \(36\).
