Answer:
The answer to your question is:
Step-by-step explanation:
12.-
x² - 6x = 5
x² - 6x + (3)² = 5 + (3)²
x² - 6x + 9 = 5 + 9
(x - 3)² = 14
13.- x² - 6x = 12
x² - 6x + (3)² = 12 + (3)²
x² - 6x + 9 = 12 + 9
(x - 3)² = 21
x - 3 = ±√21
x1 = √21 + 3 x2 = -√21 + 3
x1 = 7.58 x2 = -1.58
14.- 2x² - 24x = - 20 Divide by 2
x² - 12 x = -10
x² - 12x + (6)² = - 10 + (6)²
x² - 12x + 36 = - 10 + 36
( x - 6) ² = 26
x - 6 = ±√26
x1 = √26 + 6 x2 = -√26 + 6
x1 = 11.1 x2 = 0.9

The amount Howie will pay back at the end of one year is $26000.00
The given parameters are:
-- the principal amount
-- the interest rate
--- the duration
The amount to pay back in this duration is then calculated using:
![A = P(1 + RT)](https://tex.z-dn.net/?f=A%20%3D%20P%281%20%2B%20RT%29)
So, we have:
![A = 25000(1 + 4\% \times 1)](https://tex.z-dn.net/?f=A%20%3D%2025000%281%20%2B%204%5C%25%20%5Ctimes%201%29)
![A = 25000(1 + 4\% )](https://tex.z-dn.net/?f=A%20%3D%2025000%281%20%2B%204%5C%25%20%29)
Express percentage as decimal
![A = 25000(1 + 0.04)](https://tex.z-dn.net/?f=A%20%3D%2025000%281%20%2B%200.04%29)
![A = 25000(1 .04)\\](https://tex.z-dn.net/?f=A%20%3D%2025000%281%20.04%29%5C%5C)
Multiply
![A = 26000](https://tex.z-dn.net/?f=A%20%3D%2026000)
Hence, the amount to pay back is $26000.00
