Answer:
Step-by-step explanation:
Solve the equation for 1 and 5:
1^2 +4 = 1+4 = 5
5^2 + 4 = 25 +4 = 29
Find the difference:
29 -5 = 24
Find the difference of the X values: 5-1 = 4
Rate of change is the change in Y over the change in X:
The rate of change would be: 24/4 = 6
Its a square.
So 5n = n + 16
Therefore 4n = 16 (taking one n from each side).
So n = 16/4 which is simplied as : 4.
Double check by putting 4 in the equation where n is, and it makes sense, so that is the right answer.
Your answer is c.
