In the equation \(1.5x + 54 = h\), the variable \(x\) represents the number of years since the tree was planted. This is because the term \(1.5x\) indicates the growth of the tree over \(x\) years at a rate of 1.5 inches per year, while 54 represents the initial height of the tree at the time it was planted.
Therefore, the correct answer is:
C. The \(x\) represents the number of years since the tree was planted.
Therefore, the correct answer is:
C. The \(x\) represents the number of years since the tree was planted.
