Mean is all the numbers added divided my the number of numbers 6+6+6+5+5+6+5+6+5/9 5.55 median is the middle number 6 mode is the number that occurs the most 6 Range is the maximum minus the minimum 6-5 1
If I am reading the question correctly it would come out to -6x+42 First do all the addition and squaring, then factor in that negative. You come out to -2x^3 +2x^3-4x-2x+25+5+9+3. The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
