If the perimeter of this figure is 78 cm, what is the value of x?F −12G −6H 6J 12

9 One type of redwood tree has an average height of 65 feet when it is 20 years old. If the tree is more than 20 years old, the average height, h, can be modeled by the function h=1.95(a−20)+65, where a is the age of the tree in years. Which statement about this situation is true?A Every additional 1.95 ft of length over 20 ft adds 45 years to the age of this type of redwood tree.B For this type of redwood tree, the average height increases by 1.95 ft per year throughout its lifetime.C Each additional year of age over 20 years adds 1.95 ft to the average height of this type of redwood tree.D For this type of redwood tree, the average height increases by 65 ft for every 20 years of growth.

12 The length, in feet, of a small train at an amusement park can be modeled by the function f(c)=9c+14, where c is the number of passenger cars attached to the locomotive. The original passenger cars were replaced, and the length of the train is now modeled by the function h(c)=12c+14. Based on this information, which statement describes the change in this situation?F The locomotive is now 9 feet long, and the length of each passenger car remained the same.G The locomotive is now 12 feet long, and the length of each passenger car remained the same.H Each passenger car is now 9 feet long, and the length of the locomotive remained the same.J Each passenger car is now 12 feet long, and the length of the locomotive remained the same.
