Answer:
Step-by-step explanation:
so theres 8 red marbles, 6 blue marbles, and 6 white marbles so that makes
8 + 6 + 6 = 20 marbles in total
the probability of the marble being white is 6/20 or 3/10
so the probabilty of the marble NOT being white is 1 - (3/10) = 7/10
It’s easy do 2 times 14 so it’s 28

the answer would be 16380

Answer:
c. 
Step-by-step explanation:
Since the divisor is in the form of
, use what is called Synthetic Division. Remember, in this formula, <em>-c</em> gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:
4| 3 −11 −4
↓ 12 4
_______________
3 1 0 → 3x + 1
You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [3x² - 11x - 4]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 3 in your quotient can be a 3x, and the 1 follows right behind it, giving you the quotient of
