Mean is the average of all the numbers so you add them all together and the amount of numbers you added together you divide that by the addition to get the mean. The mean for those 4 numbers is 11,299. Hope I helped!
The answer is 8x I believe
Because there are no parentheses, I'm assuming you're asking for how to factor this using the GCF, which can be done like so:
9−12x+6y
Factor a 3 out of this expression.
3(3 - 4x + 2y)
The expression has been simplified using the distributive property in reverse.
