Solve the equation by completing the square. x²+6x-4=0​
zavuch27 [327]

Answer:

<u>x = √13 - 3</u>

<u>x = -√13 - 3</u>

Step-by-step explanation:

Given :

  • x² + 6x - 4 = 0

Solving :

  • x² + 6x + 9 - 9 - 4 = 0 [Adding and subtracting 9]
  • (x + 3)² - 13 = 0 [Group the square term together]
  • (x + 3)² -13 + 13 = 0 + 13 [Add 13 on both sides]
  • √(x + 3)² = √13 [Taking square root on both sides]
  • x + 3 - 3 = ±√13 - 3 [Subtract 3 from both sides]
  • x = ±√13 - 3

Solutions :

  1. <u>x = √13 - 3</u>
  2. <u>x = -√13 - 3</u>

The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of 12. Find the mean for the number
Sever21 [200]

Answer:

mean = 8.4

Step-by-step explanation:

Mathematically, we have the mean as np

This is the product of the number of items per batch by the probability that each of the products will germinate

Mathematically, we have this as:

0.7 * 12 = 8.4
