-424 +122-72+2

Jason tried to find an expression equivalent to the rational expression

by using

202+1

polynomial long division. His work is shown below.

- 2x + 7x

2x + 1) - 4x4 + 12x3 - 7x + 2

-(-4x4 - 2x2)

14x - 7x + 2

- (14x3 + 7x)

-14x + 2


Jason concluded that -202 + 7+ +

-142+2

was equivalent to the rational expression. Jason's

2x+1

conclusion is incorrect.

O He made a mistake subtracting - 4x4 - 2x² from - 4x4 + 12x² - 7x + 2

He made a mistake by multiplying 2x² + 1 by 2x2

O He made a mistake subtracting 14x + 7x from 14x3 – 7x + 2

O He should have done one more step of long division to divide - 14x + 2 by 2x² + 1

Answers

Answer:

The expression "-424 +122-72+2" doesn't seem to have anything to do with the rest of the problem.  The sum of what was written is -372.  There are no unknowns (x's) in this expression, and yet the work shows x's in the analysis.

Step-by-step explanation:

What does "by using

202+1

polynomial long division."  mean??

do the numbers after the x's represent exponents?

e.g.:  "2x + 1) - 4x4 + 12x3 - 7x + 2" is really "2x + 1) - 4x4 + 12x^3 - 7x + 2"

Parmi les rectangles de périmètre 100cm, quelles sont les dimensions du rectangle d'aire maximale?

Merci d'avance, Joudy :))

Answers

La solution:

625 cm^2.

Explication étape par étape:

Si la forme est rectangulaire, elle aura la plus grande superficie possible quand la longueur équivaut à la largeur. Pour avoir un périmètre de 100 cm, cela signifie que chaque côté doit faire 25 cm.

La superficie serait alors de 25 cm x 25 cm = 625 cm^2.

If 10 plus 2 equals 12 the what does 10 times 8 times 12 times 1 mean

Answers

Answer:

960

Step-by-step explanation:

(10 + 2) = 12

"10 times 8 times 12 times 1"

what does 10 times 8 times 12 times 1 mean

10  *   8   *  12  * 1 = (10)(8)(12)(1)

                            =   (80) * 12

Answer:

y=10/3

Step-by-step explanation:

Answer:

y = - [tex]\frac{24}{7}[/tex]

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 6 when x = - 7

6 = - 7k ( divide both sides by - 7 )

- [tex]\frac{6}{7}[/tex] = k

y = - [tex]\frac{6}{7}[/tex] x ← equation of variation

When x = 4 , then

y = - [tex]\frac{6}{7}[/tex] × 4 = - [tex]\frac{24}{7}[/tex]

What is the solution to the equation? −12x=−3 Enter your answer as a simplified fraction in the box. x =

Answers

Answer:

1/4

Step-by-step explanation:

This is because you want to get x alone, so if you divide -12 on one side you have to do it on the other side, so you get -3/-12 which can be divided by -3 to be simplified to 1/4. Hope this helps!

Answer:

1/4

Step-by-step explanation:

-12x = -3

x = 12 : -3

x = 1/4

What is an equation of the line that passes through the points (4, -1) and (8, 5)?

Answers

Answer:

y=3/2x-7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(5-(-1))/(8-4)

m=(5+1)/4

m=6/4

simplify

m=3/2

y-y1=m(x-x1)

y-(-1)=3/2(x-4)

y+1=3/2(x-4)

y=3/2x-12/2-1

y=3/2x-6-1

y=3/2x-7

Step 2. Multiply the first fraction by that reciprocal.

Step 3. Simplify the fraction (if needed).

A shoe store donated a percent of every sale to hospitals. The total sales were $9,950 so the store donated $796. What percent of 9,950 was donated to hospitals?

Answers

Answer:

8%

Step-by-step explanation:

when solving with percentages, you can “cross multiply”,

we know the fraction would be set up this way:

[tex]\frac{769}{9950}*\frac{x}{100}[/tex]

*there would be an 100 bc a percentage is out of 100*

Now, you have to multiply 769 by 100

[tex]769*100=\\ 76900[/tex]

Then divide by 9950 to get “x”

[tex]79600/9950=\\ 8[/tex]
