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 height h

1.5x + 54 = h

what does the x repersent in this equation

1 answer

In the equation \( 1.5x + 54 = h \), the variable \( x \) represents the number of years since Marco planted the tree. As time passes, the height of the tree \( h \) increases by 1.5 inches for each year, starting from the initial height of 54 inches.
