Sadly, you didn't put any sums on your list of choices.
In fact, I can't even find a list of choices !
To find the distance between (7, -1) and (-8, -9),
you would build a sum under a square-root (radical)
symbol, and it would look something like this:
√ ( 225 + 64 ) .
Answer:

Step-by-step explanation:
1. you distrubute the -4 to the -2x and +7.
2.you combine like terms.
3.you get X in one side of the equation.
4.You divide 1 by 6.

Range is {-(2)^2 + 4, -(0)^2 + 4, -(1)^2 + 4} = {-4 + 4, 0 + 4, -1 + 4} = {0, 4, 3}
For this case, the first thing we should do is observe that we have a linear equation.
Therefore, we have a sequence of the form:

Where, k: is the slope of the line.
We have then:

Substituting we have:
Answer:
An explicit formula for the sequence of the number of bacterium is:
an = 21 * n
