Answer:
Step-by-step explanation:
X² + 10x = -8
add to both side the square of half the coefficient of X which is 5²
X² + 10x + (10/2)² = -8 + (10/2)²
X² + 5² = -8 + 5²
( X + 5 )² = -8 + 25
(X + 5)² = 17
X + 5 = +- √17
Therefore, X = -5 +- √17.
X = -5 + √17 , -5 - √17.

Your answer is going to be 26 and 14, because 26+14=40, and 26-14=12.:)
Let m=n-4
n - 4 + 5n = 20
6n = 24
> n = 4
m = 4 - 4
> m = 0
(0,4)
The equation that models the sequence is: 6+6 each time.
