Use the FOIL method, or (First, Outside, Inside, Last)

2n x 2n = 4n^2
2n x (-2) = -4n
2n x (2) = 4n
2 x (-2) = -4

4n² - 4n + 4n - 4   (simplify)

4n² (-4n + 4n) - 4

-4n + 4n = 0

4n² - 4 is your answer

hope this helps

A furniture maker uses the specification 19.88
dimulka [17.4K]

Answer:

The correct answer is:

w-12 20

Explanation:

We first find the average of the two ends of the inequality:

(19.88+20.12)/2 = 40/2 = 20

This will be the number subtracted from w in the inequality.

Now we find the difference between this value and the ends:

20-19.88 = 0.12

20.12 - 20 = 0.12

This will be what our absolute value inequality ends with; the "answer" part, so to speak.

Since this inequality is written in compact form, it must be an "and" inequality; this means the absolute value inequality must be a "less than or equal to."

This gives us

w -12 20

A loan of $16,840 is borrowed at 9% simple interest and is repaid with $4,167.90 interest. What is the duration of the loan?​
rewona [7]

9514 1404 393

Answer:

  2 3/4 years

Step-by-step explanation:

The interest is given by the formula ...

  I = Prt . . . . . . principal P at annual rate r for t years

Solving for t gives ...

  t = I/(Pr)

  t = 4167.90/(16840×0.09) = 2.75

The duration of the loan is 2 3/4 years.

The graph of the piecewise function f(x) is shown.
iris [78.8K]
1. The range of a function is the set of all values that f can produce for all the x-es in the domain.

2. If we are given the graph, in order to find the range, we project the graph into the y axis. Informally, we draw the "shadow" of the graph into the y axis as in the FIGURE atached.

3. The range is <span>D || {y | −5 ≤ y ≤ −1}</span>
