Answer and explanation:
Given : The demand for a product for the last six years has been 15, 15, 17, 18, 20, and 19. The manager wants to predict the demand for this time series using the following simple linear trend equation : 
To find : What are the forecast errors for the 5th and 6th years?
Solution :
Data : 15, 15, 17, 18, 20, and 19.
The simple linear trend equation is given as, 
For t = 5 years



Observed 
Predicted 
Forecast error = Observed – Predicted = 20 – 22 = -2
Absolute forecast error = |-2| = 2
.
For t = 6 years



Observed 
Predicted 
Forecast error = Observed – Predicted = 19 – 24 = -5
Absolute forecast error = |-5| = 5.

Can I get the length of the two other sides or a picture of it so I can answer
Answer:
2
Step-by-step explanation:
Coefficients are always the number being multiplied by (or attached to) the variable, which is shown by a letter
so in 2x, 2 is the coefficient, and x is the variable
