Answer:
2 (x + 3)^2 - 2
Step-by-step explanation:
1. Factor the 2 out of the equation (don't forget about it - it will be used later). This gives you x^2 + 6x + 7
2. Subtract the 7 over. This gives you x^2 + 6x = -7
3. Take b (6), divide it by 2 (3), and square it (9). Then add that to both sides of the equation. This gives you x^2 + 6x + 9 = 2
4. Factor the left side of the equation. This gives you (x + 3)^2 = 2
5. Subtract the 2 over. This gives you (x + 3)^2 - 2
6. Remember that 2 we factored out of the equation earlier? Well that goes in front of the parentheses now, giving you the final answer of 2 (x + 3)^2 -2
=1,400 because i worked the problem out
67 & 513,000
I got this because when your putting them together then you sixty seven so 67.
Answer:
138,456
Step-by-step explanation:
Each year, the cost is multiplied by 1 +5% = 1.05. In 10 years, it will have been multiplied by that factor 10 times, so will be ...
85,000×1.05^10 ≈ 138,456
The cost of living in 10 years will be about 138,456 per year.
