Plz me i been on these for like an hour

First, keep in mind that two negatives make a positive:

-13w^2 + 13 + 2w^2

-11w^2 + 13

To solve this problem, the first thing we should do is eliminate the parentheses in the expression.  To do this, we must understand that subtraction of a negative equals a positive, meaning that we can get rid of the second set of parentheses and change the minus a negative to a plus sign.  If we do this, we get:

(-13w² + 13) + 2w²

Next, we can get rid of the parentheses around the first two terms because there is addition inside and outside of the parentheses.  Since there ins no multiplication or negatives, we can simply rewrite the same expression with no parentheses.

-13w² + 13 + 2w²

Now, we must combine like terms.  This means adding terms that have the same variable to the same degree.  in this case, we must add -13w² and 2w².  To do this, we simply add their coefficients, giving us:

-11w² + 13

Therefore, the expression directly above is your answer.

Hope this helps!

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
