12 out of 18. This is because there is 6 red marbles and 18 of them all together. The question states the probability of the red marble NOT being chosen therefore you need to take away 6 from 18 leaving you with 12. I hope this made sense :)
the domain is your x values so it is B
Answer:

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
Step-by-step explanation:
Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.
If the garden is X yards long, express the Gardens area as a function of length
Let x be the length of garden
So perimeter of rectangle = 60 yard
Perimeter = 2 * ( Length + width)
60 = 2 * ( x + width)
Width = 60/2 - x
Width= 30 - x

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
