645/8= 80.625 lol why do u even need this
2x + 4 = 3(x - 2) + 1
2x + 4 = 3x - 6 + 1
2x + 4 = 3x - 5
9 = x
So x = 9
Answer:
![\large\boxed{5x^2+6x-8=(x+2)(5x-4)}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B5x%5E2%2B6x-8%3D%28x%2B2%29%285x-4%29%7D)
Step-by-step explanation:
![5x^2+6x-8\\\\=5x^2+10x-4x+8\\\\=5x(x+2)-4(x+2)\\\\=(x+2)(5x-4)](https://tex.z-dn.net/?f=5x%5E2%2B6x-8%5C%5C%5C%5C%3D5x%5E2%2B10x-4x%2B8%5C%5C%5C%5C%3D5x%28x%2B2%29-4%28x%2B2%29%5C%5C%5C%5C%3D%28x%2B2%29%285x-4%29)
If it decreases at 4% every year, then its value becomes:
100% - 4% = 96% = 96/100 = 0.96
At the end of the 1 year its value becomes: 150*(0.96)
At the end of the 2 years its value becomes: 150*(0.96)*(0.96) = 150*(0.96)²
At the end of the 3 years its value becomes: 150*(0.96)*(0.96)*(0.96) = 150(0.96)³
So similarly at the end of 12 years, its value becomes 150*(0.96)¹²
=50*(0.96)¹² simplify with calculator.
<span>≈ 91.91
Value at the end of 12 years becomes ≈ $</span><span>91.91
I hope this helps.

Answer:
x = 12
Step-by-step explanation:
Given
+ 2 = 8 ( subtract 2 from both sides )
= 6 ( multiply both sides by 6 )
3x = 36 ( divide both sides by 3 )
x = 12
