Which expression is equivalent to 2x2 – 18? A. (2x – 3)2
B. 2(x - 3)2
C. (x + 9) (x - 9)
D. 2(x+3)(x – 3)

D. 2(x+3)(x – 3)

Step-by-step explanation:

Simplify the expression.

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.

differentiate (x^14(x^-2)^4with respect to the variable

the parentheses don't balance in your input.

differentiate 0 with respect to

the final answer is

0
