Subtracting 3x^2+4x-5 from 7x^2+x+9 results in polynomial. after subtracting 4x^2-3x from this polynomial the difference is

the answer is 4

Step-by-step explanation:

when you subtract 3x^2+4x-5 from 7x^2+x+9, you'd get 4x^2-3x+4. you subtract 4x^2-3x from that, you're left with 4

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
