Use long division to rewrite the quotient in an equivalent form as , where is the quotient, is the remainder, and is the divisor.

Answers

Answer:

x+2 + (-5x+4)/(x^2-2x+1)

See attached

Step-by-step explanation:

Equivalent expression to represent the given division in quotient , remainder and divisor form is equals to [tex](x+2)+\frac{-5x+4}{x^{2} -2x+1}[/tex].

What is division?

" Division is defined as the distribution of the given quantity into equal parts as per the conditions apply."

According to the question,

Given expression,

[tex](x^{3} -8x+6)[/tex] ÷ [tex](x^{2} -2x +1)[/tex]

As shown in long division we get,

Quotient [tex]q(x) = x+2[/tex]

Remainder [tex]r(x) = -5x+4[/tex]

Divisor [tex]b(x) = x^{2} -2x +1[/tex]

Represent quotient , remainder and divisor in an equivalent form of given expression we get,

[tex](x^{3} -8x+6)[/tex] ÷ [tex](x^{2} -2x +1)[/tex] = [tex](x+2)+\frac{-5x+4}{x^{2} -2x+1}[/tex]

Hence, equivalent expression to represent the given division in quotient , remainder and divisor form is equals to [tex](x+2)+\frac{-5x+4}{x^{2} -2x+1}[/tex].

Answer:

D. 329

Step-by-step explanation:

119 can be expressed as the factors of 2 prime numbers: 7 and 17.

There would be no need to further simplify the expression if x does not have one of these factors.

We can check that D is the only one that has one of these factors: 7, since 329/7 = 47.

Step-by-step explanation:

1. Put the value of x in the expression and see what the angle measure is.

  m∠A = 4x +12 = 4(15) +12 = 60 +12 = 72

The angle is less than 90°, so is acute.

2. The measure of a right angle is 90°, so you have ...

  4x +22 = 90

  4x = 68 . . . . . subtract 22; next, divide by 4

9. Tony bought x boxes of cookies to bring to a party. Each box has 28 cookies. He decides
to keep 2 boxes for himself. He brings 84 cookies to the party.
Which equation can be used to find the number of boxes Tony brought to the party?
A. 2x - 28 = 84
B. 28x - 2 = 84
C. 28x – 56 = 84
D. 56 – 28x = 84

Answers

The correct answer is C. 28x – 56 = 84

Explanation:

Writing an equation using a description or situation involves including all the factors mentioned and relating these appropriately through mathematical symbols. In the case presented, the correct equation is 56 – 28x = 84. This is because this equation includes the total of boxes Tony took to the party 84 and this has been correctly included after the symbol =. Also, the total of boxes is equal to the boxes tony bought each with 28 cookies, which can be represented as 28x (x represents the value of boxes that multiplied by 28 leads to the total of cookies) minus the cookies Tony bought (2 boxes each with 28 cookies). This makes the final equation to be 28x – 56 = 84.

DO you know the answer ? help me out if you can

Answers

Answer:

The answer would be B. Benefit would decrease by $7,020 annually

Step-by-step explanation:

One way you can find a percentage of any number is to take the percentage and move the decimals to the left twice, 13% into 0.13. With this decimal you would multiply it by the main number you want the percentage from, $54,000. 0.13 × 54,000 would give you a product of 7,020 thus your answer.

This isn't completely necessary but if you would like to check your answer you could do this process backwards, to do such you would take your answer you received, 7,020, and divide that by your main number, 54,000. The quotient would be your percentage as a decimal 7,020 ÷ 54,000 = 0.13. Thus meaning your answer is correct.

lim x>-1 x^2-x-2/x+1

Answers

Answer:

-3

Step-by-step explanation:

If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.

In this case, factoring the polynomial at the top would be helpful.

The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)

The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:

-1-2 = -3

Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.

I hope this helped you.
