Do you know the distribution property? I can't explain why you have to do that, but google search it. the number that is outside of the parenthesis will be multiplied in <em>each </em>of the number in the parenthesis.

-8(-8b-6) = -6b-22

the distribution property will look like this

-8 * -8b = 64b

-8 * -6 = 48

(two negative numbers make a positive)

now th equation will look like this

64b + 48 = -6b-22

you must have the variable to one side of the equation. That means you need to subtract one of them to the other side or add it depending if the number is positive or negative. For example, you can add 6b to 64b (the opposite operation of -6b is addtion making -6b a positive number) so 64b + 6b - 70b

70b + 48 = -22

solve b!

Robert plans to make a box-and-whisker plot of the following set of data. 27, 14, 46, 38, 32, 18, 21 Which of the following shou

Simora [160]

To make a box and whisker plot, you need to draw a number line that would be able to represent all the values in the data (look at your lowest and highest numbers).

You will need to graph the following 5 points on your number line (median, lower quartile, lower extreme, upper quartile, and upper extreme).

Create a box around the quartiles and extend the lines to the extremes.
See the picture I have attached for the box and whisker box for this data set.
