Answer:
f=54
Step-by-step explanation:
ma is m times a 3x18= 54
Answer:
Step-by-step explanation:
A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
For this case we have a quadratic polynomial given by:

Where:

We must factor, for this we follow the steps below:
Step 1:
The term of the medium must be rewritten as the sum of two terms, whose sum is -7 and the product is
:
Then, the term of the medium, fulfilling the two previous conditions, can be written as:

We check:

So, we have:

Step 2:
The maximum common denominator (the largest integer that divides them without leaving residue) of each group is factored

Step 3:
We take common factor
:

Thus, the expression
can be factored as:

Answer:

C. The numbers would alternate between Positive and Negative
