Yesterday, Chang planted 6 trees that were each 8 feet tall in his yard.  Chang projects the trees to grow at the following annual rates over the next 5 years.

Tree
Rate
Sycamore
2.5 feet
Sugar Maple
15 inches
Red Maple
3 feet
Fraser Fir
3 inches
Linden
1.5 feet
Oak
4 feet

Assume that x represents the amount of years from when Chang planted the trees.  Which of the following equations represent the height of each of the trees in 5 years?  Select all that apply.

Sugar Maple
8 + 1.5x = 15.5

Fraser Fir
8 + 0.25x = 9.25

Sycamore
8 + 2.5x = 12.5

Red Maple
8x + 3 = 43

Oak
8 + 4x = 28

Linden
8x + 1.5 = 9.5
