Answer:

Step-by-step explanation:
The mode is the value which occurs the most.
Stem = 3 and leaf = 1, 1,6 so that is 2 31's.
Answer:
9x-3x(2-4)=6x(3x+4)-6(3x-2)
If you add 2 odd numbers together eg. 5+5 it would become an even number eg. 10.
If you add 2 even numbers together eg. 60+60 it would stay as an even number eg.120.
The product is basically the same thing as that but instead of adding the same number twice, you multiplying the number with 2 which is the same as adding two of the same numbers.
28 = k - 12
28 + 12 = k
40 = k
