First you use the distributive property. So, 3 times 1 and 3 times -xx = 2 times -4x and 2 times 7. This becomes 3-9x = -8x+14. Subtract 3 from both sides and add 8x to both sides and you get -x=11, so x=-11

A interesection B means similarities between the two sets.
The possible values you can get in B are:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

A:
3, 5, 7, 9, 11

Therefore A intersection B = {3, 5, 7, 9, 11}

frez [133]

Answer:

Mode = 81, Median = 81 and Range = 39.
