There are two zeros: -3 and -1. This is because when you factor f(x)<span>= x^2 + 4x + 3, it becomes f(x) = (x + 3)(x + 1). In order to find the zeros, set f(x) to 0, and then solve for x for both (x + 3) and (x + 1). You can check your answer by substituting either -3 or -1 for x in the equation 0 = </span>x^2 + 4x + 3.
The sum of angles for any triangle is 180°. So x=180-19-(180-51)=32°
6 / 8 = 3/4
3/4 x 7 = 5 1/4
5 1/4 = $5.25
So, 7/8 of a pound of shrimp costs $5.25.
Answer:

Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)


If the three are to be next to each other,
First, we arrange the three

Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:

So, the total arrangement, when they have to be next to one another is:


The probability is:
