(3x^2+9x-6) - (2x^3-4x^2+6x-4)
Short Answer
2x^3+7x^2+3x-2

Step by Step
1.)2x^3 doesn’t subtract from anything because there are no other trinomials

2.)3x^2 - (-)4x^2 = 7x^2 because a double negative cancels out and you end up adding them

3.)9x-6x=3x

4.)-6 - (-)4 = -2 because double negatives cancel out into addition

The display that would best show the measures of variation of the given prices is; B: Box and Whisker Plot

<h3>What is the importance of Box and Whisker Plot?</h3>

We are given the prices of Phone chargers in a store as;

$19, $18, $15, $17, $19, $12, $19, and $15.

Now, since we want to determine the display that would best show the measures of variation, the best display would be a box and whisker plot. This is because Box and Whisker plots are a great chart to use when showing the distribution of data points across a selected measure. These  box and whisker plots display ranges within variables measured.
