Use the long division method to find the result when x^3+7x^2+12x+6x 3 +7x 2 +12x+6 is divided by x+1x+1. If there is a remainde

Aliun [14]

Answer:

By long division (x³ + 7·x² + 12·x + 6) ÷ (x + 1) gives the expression;

$x^2 + 5 \cdot x + 7 - \dfrac{1}{(x + 1)}$

Step-by-step explanation:

The polynomial that is to be divided by long division is x³ + 7·x² + 12·x + 6

The polynomial that divides the given polynomial is x + 1

Therefore, we have;

$\ \ \ \ \ \ \ \ \ \ \ \ x^2 + 5\cdot x + 7\\ (x + 1) \sqrt{x^3 + 7\cdot x^2 +12\cdot x + 6} \\\ {} \ {} \ {} \ \ {} \ {} \ {} \ {} \ {} \ {} \ {} \ \ x^3 + 2 \cdot x^2 \\\ \ \ \ {} \ \ {} \ {} \ {} \ \ {} \ {} \ \ \ {} \ {} \ {} \ \ {} \ {} \ {} \ \ 5 \cdot x^2 + 12\cdot x + 6\\ \ {} \ {} \ {} \ {} \ {} \ {} \ \ {} \ {} 5 \cdot x^2 + 5\cdot x\\\ 7\cdot x+6\\7\cdot x+7\\-1$

(x³ + 7·x² + 12·x + 6) ÷ (x + 1) = x² + 5·x + 7 Remainder -1

Expressing the result in the form $q(x) + \dfrac{r(x)}{b(x)}$ , we have;

$(x^3 + 7\cdot x^2 + 12 \cdot x + 6)\div (x + 1) = x^2 + 5 \cdot x + 7 - \dfrac{1}{(x + 1)}$

500x+6y=11216. and 800x+4y=9344 solve substuition method

Sedaia [141]

we have

$500x+6y=11,216$ ---------> equation $1$

$800x+4y=9,344$ ---------> equation $2$

<u>In the equation $1$ clear variable x</u>

$500x+6y=11,216\\ 500x=11,216-6y$

$x=22.432 -0.012y$ ----------> equation $3$

Substitute the equation $3$ in the equation $2$

$800*[22.432 -0.012y]+4y=9344$

$800*[22.432 -0.012y]+4y=9,344\\17,945.6- 9.6y+4y=9,344\\9.6y-4y= 17,945.6-9,344\\ 5.6y=8,601.6\\y=8,601.6/5.6\\y= 1,536$

<u>Find the value of x</u>

$x=22.432 -0.012y$

$x=22.432 -0.012*1,536$

$x=4$

therefore

<u>the answer is</u>

$x=4$

$y=1,536$

Tony measures a drum stick and gets a length of 31 centimeters kate converts tony's measurements and gets 3.1 is her answer reas

laila [671]

Answer:

Kate has changed the unit of measurement from centimeters to decimeters.

Step-by-step explanation:

Tony measures a drum stick and the length is measured to be 31 centimeters.

Now, Kate converts Tony's measurements and gets 3.1.

Now, we know that 10 centimeters are equivalent to 1 decimeter.

Hence, 1 centimeter will be equivalent to 0.1 decimeters.

And, 31 centimeters will be equivalent to 31 × 0.1 = 3.1 decimeters.

So, Kate has changed the unit of measurement from centimeters to decimeters. (Answer)

Please help me!<br><br> Solve for x : show your steps!<br><br> 2(x +8) = 4(x+2)

Tju [1.3M]

Answer:

4

Step-by-step explanation:

First, use the distributive property: 2x+16=4x+8

Second, move +8 to the other side(and turn it negative): 2x+8= 4x

Do the same for +2x: 8=2x

divide both sides by 2: 4=x
