Which equation has the same solution as x^2-6x-14=0

B

Step-by-step explanation:

Given

x² - 6x - 14 = 0 ( add 14 to both sides )

x² - 6x = 14

Use the method of completing the square on the left side of the equation

add (half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + (- 3)² = 14 + (- 3)²

x² - 6x + 9 = 14 + 9 ← left side is a perfect square, hence

(x - 3)² = 23 → B

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
