Average rate of change from x = 0 to x = 1 is

Average rate of change from x = 2 to x = 3 is

The average rate of change of both sections are equal.
T and g are the answer because you can’t do 10x and 15
I don't really get what you are asking for. Can you clarify it?
Answer:Obtain a systematic sample by selecting every 20th vehicle that passes (in any lane and going in any direction).
Step-by-step explanation:
The midpoint lines are half the opposite side length.
Line DE is given as 7 , So Line F = 7 x 2 = 14
Line EF is given as 12, so Line D = 12 x 2 = 24
Line DF is given as 16, so line E = 16 x 2 = 32
The perimeter is the sum of the 3 sides:
Perimeter = 14 + 24 + 32 = 70
