Axis of symmetry -3 and -8 or 3 and -8
Answer:
b
Step-by-step explanation:
The dimensions of the base of Box 1 are x by 3x.
The base area of Box 1 is:
3x^2
The temperature starts at 85 degrees.
t = 85
After 1 minute, it loses 3.5 degrees.
t = 85 - 3.5
After 2 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 2
After 3 minutes, it loses another 3.5 degrees.
t = 85 - 3.5 * 3
etc.
After 12 minutes, it loses another 3.5 times 12 degrees.
t = 85 - 3.5 * 12
