Answer: For the first question, the answer is 9. For the second question, the answer is 6x-6. For the third question the answer is 9. For the fourth question the answer is also 9.
Step-by-step explanation: There is nine numbers between k and m. By distributing the 2, you get 2x-6+4x, which, by adding, you get 6x-6. The absolute value of 6 is 6 and the absolute value of -3 is 3, so 6+3=9. Two negatives equal a positive, so [-(-4)] is the same as 4, so 4 plus 5 equals 9.
