The distributive property: a(b + c) = ab + ac
12(6k + 3) + 4(7 - 5k) = 12(6k) + 12(3) + 4(7) + 4(-5k)
= 72k + 36 + 28 - 20k = 52k + 64
Independent variables (IV): These are the factors or conditions that you manipulate in an experiment.
Dependent variable It is something that depends on other factors
A constant is a value or number that never changes in expression; it's constantly the same.
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results.
I hope I was helpful
8500 x 6.5 x 10 + 8500 =
8500 x 6.5 + 8500 =
8500 x 6.5/100 + 8500 =
8500 x 13/20 + 8500 =
110500/20 + 8500 =
5525 + 8500 =
14025
M=0, -13
hope that helps! :)
the first six terms of the sequence 
now on this new edited version
so, as you can see, the "common difference" of this arithmetic sequence is d = 5, hmmm what term is 67 anyway?
