State whether the graph of each linear realation ship is a solid line or a set of unconnected points explain your reasoning
the relationship between the height of a tree and the time since the tree was planted

The graph of  each linear relationship is a solid line.

     The graph of the given  linear relationship i.e.

The relationship between the height of a tree and the time since the tree was planted is:

A solid line since the height of a tree planted is continuous as the height of a tree increases continuously increases  or may remain constant in some time interval and hence the graph is a solid line.

Step-by-step explanation:

First we can write the equation to find the surface area of a rectangular prism

Now rewrite filling in variables

Solve. Keep in mind the order of operations

After solving, you should get 158.

Since these measurements were done in inches, we need to add inches/in to the end.

Also, since it is area, we need to add ²

158 in²
