Answer:No its not a function
Step-by-step explanation:
Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20
So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm
Answer: Length=77 cm and width=20 cm
Relative frequency is the number of times that the train is late between the total of journeys, so only multiply 0.15*100 =15 times
option : c. 2x + 15 = 145
cuz, the angles are vertical opposite angles
