There are three trees in Eddy's backyard. The shortest tree has a height of 6 feet, and the second tree has a height of 5 feet more than the shortest tree. The height of the tallest tree is twice the height of the two trees combined. How tall is the tallest tree?

How tall is the second tree? ** The height of the second tree is 6 + 5 = <<6+5=11>>11 feet.
How tall are the two trees combined? ** Thus, the combined height of the two trees is 6 + 11 = <<6+11=17>>17 feet.
How tall is the tallest tree? ** Therefore the height of the tallest tree is 2 x 17 = <<2*17=34>>34 feet.
