You are trying to figure out what is n.
so you would move all the terms that contain "n", to the right side and solve the problem to get 9
so n=9
Answer:
x = -1 ± √3
Step-by-step explanation:
3x² − 2x − 1 = x² − 6x + 3
Move everything to one side.
2x² + 4x − 4 = 0
Divide by 2.
x² + 2x − 2 = 0
Solve with quadratic formula, or by completing the square.
x² + 2x = 2
x² + 2x + 1 = 3
(x + 1)² = 3
x + 1 = ±√3
x = -1 ± √3
I got this as my answer maybe it will help

Answer:
$6,824.03 is the amount the family will spend on vacations in 5 years
Step-by-step explanation:
The formula A = P(1 + r)^n is appropriate in this problem, with the understanding that A represents the amount the family will spend on vacations in n years and P is the current spending amount. Then:
A = ($7,845)(1 - 0.0275)^5, where we use -0.0275 to indicate that the amount DECREASES by 2.75% annually. Simplifying this formula, we get:
A = ($7,845)(0.9725)^5, whose value to the nearest cent comes out to:
A = $6,824.03 is the amount the family will spend on vacations in 5 years.
