Marco planted a tree that was 54 inches tall several years ago. The tree has grown at a rate of approximately 1.5 inches per year. Marco uses this equation to calculate the tree’s height, h

Question

.

What does the
x represent in this equation?

A.
The
x represents the tree’s growth each year.

B.
The
x represents the height of the tree today.

C.
The
x represents the number of years since the tree was planted.

D.
The
x represents the starting height of the tree.

Answer 1

In the context of the equation Marco uses to calculate the tree’s height, h, where the tree was initially 54 inches tall and grows at a rate of 1.5 inches per year, the variable \( x \) 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.
