(x + 5) is a factor of x2 + 2x – 15. What is the other factor?

(x-3)

Step-by-step explanation: First look what which two numbers would multiply to -15 and add to 2. In this case, it's 5 and -3 because 5x-3=15 and 5+(-3)=2.

So the other factor is (x-3)

To check your work, simply multiply

(x+5)(x-3) = x2 + 2x - 15

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
