To simplify, you must distribute the 2 into the 5x and -4 by multiplying 2 with 5x and 2 with -4.
<span>2(5x – 4) + 3x
2 x 5x = 10x
2 x -4 = -8
You will get 10x - 8 + 3x
Now you must combine like terms or add like terms. In this case we must add 10x and 3x
10x + 3x = 13x
Finally the answer would be 13x - 8</span>

I'm not sure about this question. There is so many positive integers and try to search it on Google. That might be a lot of integers to count.
Answer:
(c)
Step-by-step explanation:
As given in the statement, we have:
Out of 4 games pieces, 1 is winner.
Probability to win =p=
Jeff has game pieces = n = sample size = 4
As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :
Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)
put n = 4, p =
P (X = 1) =
P =
Which is the probability that he wins exactly 1 prize and is option c.
