Answer:
[tex]H = 2h +35[/tex]
where H is the sum of height of two trees.
Step-by-step explanation:
We are given the following in the question:
There are two trees in John's garden.
Let [tex]h\text{ feet}[/tex] be the height of shorter tree.
The length of loner tree is 35 feet taller than the shorter tree.
Thus, the height of longer tree is given by
[tex](h+35)\text{ feet}[/tex]
Sum of the two trees heights =
[tex]H = h + (h+35)\\H =(h+h)+35\\H = 2h + 35[/tex]
is the required expression for sum of heights of two tree.
