Answer:

x+2

5x-2

Step-by-step explanation:

There is only 2 binomials that will multiply together that will give the given trinomial.

ax^2+bx+c

5x^2+8x-4

Goal: Find two numbers that multiply to be a*c and add up to be b.

We will use this goal to factor our trinomial.

a=5

b=8

c=-4

--------

a*c=-20

b=8

Can you think of two numbers that multiply to be -20 and add up to be 8? I hope you said 10 and -2.

So we are going to replace 8x with -2x+10x.

5x^2+8x-4

5x^2-2x+10x-4

We are going to pair the first terms together and the second two terms together like so:

(5x^2-2x)+(10x-4)

Now we are going to factor each pair.

x(5x-2)+2(5x-2)

(5x-2)(x+2)

So (x+2) is a factor of the given trinomial and (5x-2) is a factor of the given trinomial.

For the data set represented on the box plot, which region contains the most dispersed data?
Mrrafil [7]

The region that contains the most dispersed data is between the upper quartile and the median.

<h3>Which region contains the most dispersed data?</h3>

A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.  

  • Difference between the lower quartile and the median : 300 - 275 = 25
  • Difference between the upper quartile and the median : 340 - 300  = 40
  • Difference between the upper quartile and the maximum : 355 - 340 = 15
  • Difference between the minimum and the lower quartile : 275 - 250 = 25
