Solve by the using the square root property: 5x2 - 40 = 0

2sqrt(2)

Step-by-step explanation:

5x^2 - 40 = 0

=> 5x^2 = 40

=> x^2 = 40/5 = 8

=> x = sqrt(8) = sqrt(4 x 2) = 2sqrt(2)

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

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.
