Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)² = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11

Ganezh [65]

Answer: See explanation

Step-by-step explanation:

Your question isn't clear but let me help out by reframing the question .

Let's say that Mr. Jones bought 5kilograms of flour for $825. To get the price of a kilogram of flour, we will need to divide $825 by 5. This will be:

= $825 / 5

= $165

Therefore, the price of a kilogram of flour will be $165
