<h3>Answer: Division (choice B)</h3>

====================================================

If you add the two polynomials, you get

(6x^2-2)+(6x^2+2) = 12x^2

which is another polynomial.

We can rule out choice A.

----------------

If you subtract the polynomials, the same kind of story happens (but you'll get a different polynomial)

(6x^2-2)-(6x^2+2) = -4

The term -4 is a polynomial of degree 0.

We can rule out choice D.

-----------------

If you multiply the two polynomials, then you get another polynomial. Use the FOIL rule

(6x^2-2)(6x+2) = 36x^2 + 12x - 12x - 4 = 36x^2 - 4

or you could use the difference of squares rule to help expand

(6x^2-2)(6x+2) = (6x)^2 - (2)^2 = 36x^2 - 4

or you could use the box method (see Figure 1 in the attached images below)

Whichever method you use, the result is 36x^2 - 4 which is another polynomial.

We can rule out choice C. The only thing left is choice B.

-------------------

When dividing two polynomials, it is not always guaranteed to get another polynomial as a result. Use polynomial long division to calculate (6x^2-2)/(6x^2+2) and you'll get what you see in Figure 2 below. Figure 3 shows the long division table for (6x^2+2)/(6x^2-2). Both figures 2 and 3 show a nonzero remainder. The nonzero remainder means the result is not a polynomial.

NEED HELP ASAP!!
devlian [24]

Answer:we multiply by the reciprocal of a fraction when completing a division problem because it is a rule in mathematics that when you divide two fraction, you change the division sign to multiplication and flip the fraction at the right of the multiplication sign.

Step-by-step explanation:

For example if you have 4÷ 1/2. It basically means how many 1/2 can one get in 4. And the answers is 8.

Therefore multiplying by the reciprocal of a fraction when completing a division problem is a short cut method that has been tested and proven to be correct.

11) Help pls I have the answer I just need to show the work.
spayn [35]
True.
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).

To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.

23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

I hope this helps!

Estimate the annual wages for a clerk who works 50 weeks a year and earns $15 and hour
Pachacha [2.7K]

Let us assume that a person works for 8 hours a day.

Let us assume that the person works for 5 days a week.

Wage earned per hour = $15

So, wage earned in 8 hours = 15*8 = $120

Now, wage earned in 1 day = 120

So, wage earned in 5 days = 120*5 =$600

As the person works for 5 days in 1 week

So, in 50 weeks, he will work = 50*5 = 250 days

So, total number of hours he must have worked = 250*8 =2000 hours

Now, per hour wage = $15

wage in 2000 hours = 15*2000 = $30000

Hence, the estimated wage a person earns in 50 weeks = $30000
