Answer:

I believe it's 2x²-8x + 1

Step-by-step explanation:

Combine like terms

2x²- 3x - 5x + 1

2x²- 8x + 1

Step-by-step explanation:

step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.

step 2. dos must have only 2 square rootable terms and a "-" between them.

step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!

step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!

step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!

step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!

Answer:

B. 20

Step-by-step explanation:

Using the Pythagorean Theorem, you have:

[tex]a^2 + b^2 = c^2\\24^2 + 32^2 = c^2\\576 + 1024 = c^2\\1600 = c^2\\c = 40[/tex]

So you know side AB is 40 inches long. It asks the length of the midpoint to point A, so you have to do 40/2 = 20 inches

Answer:

123.6

Step-by-step explanation:

Find the area of the circle, because the four quarter circles add to one circle. The circle has a diameter of 24, so the area of it is 452.4. The square has an area of 24*24, so the area is 576. Subtract the area of the circle from the square, and you get 123.6. Hope this helps!

Answer:

2, 3, 4

Step-by-step explanation:

Renee bought 7 potatoes at the supermarket. The shortest diameter of each,  

in centimeters, is shown below.

2, 3, 4, 4, 6, 6, 7

After Renee used one potato to make dinner, the median diameter of the remaining  potatoes was 5 centimeters. Which of these could be the diameter, in centimeters,  of the potato Reneetsed?

Solution:

The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.

The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.

Given that the diameter of the potato as:

2, 3, 4, 4, 6, 6, 7

Given that after removing one potato, the median of the remaining  potatoes was 5 centimeters.

After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.

To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.

If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.

Median = (4 + 6) / 2 = 5

Answer:

x=−5 and y=−7

Step-by-step explanation:

Step: Solve y=2x+3for y:

y=2x+3

Step: Substitute2x+3foryin4x−3y=1:

4x−3y=1

4x−3(2x+3)=1

−2x−9=1(Simplify both sides of the equation)

−2x−9+9=1+9(Add 9 to both sides)

−2x=10

−2x

−2

=

10

−2

(Divide both sides by -2)

x=−5

Step: Substitute−5forxiny=2x+3:

y=2x+3

y=(2)(−5)+3

y=−7(Simplify both sides of the equation)

Answer:

-6

Step-by-step explanation:

You have to multiple -2 by 15 and -8 separately

8 - 2(15-8)

8 -30 + 16

24-30 = -6

The closest point to the number line is C.

Hence Option C is correct.

In the given number line

There are 10 equidistant points between 3.1 and 3.2

So, the set of points shown on the line is,

{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}

Therefore,

Point c represents point 3.14 approximately.

Since we know that π is an irrational number,

So it is non-terminating and non-repeating but for approximation,

π = 22/7

π ≈ 3.142

Hence,

The point C is very close to the π.

Answer:

51,200 unidades

Step-by-step explanation:

Paso 1

Calculamos el porcentaje de disminución

= 100000 - 80000/100000 × 100

= 20000/100000 × 100

= 20%

Por lo tanto, el porcentaje de disminución cada mes = 20%

Paso 2

La fórmula de la disminución exponencial

y = a (1 - r) ^ t

a = 80.000

r = 20% = 0,2

t = tiempo en meses = 2

y = 80000 (1 - 0,2) ^ 2

y = 51.200 unidades

Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.

Una función exponencial decreciente tiene el siguiente formato:

[tex]A(t) = A(0)(1 - r)^t[/tex]

En que:

En este problema:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]80000 = 100000(1 - r)^4[/tex]

[tex](1 - r)^4 = 0.8[/tex]

[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]

[tex]1 - r = 0.945742[/tex]

Por eso:

[tex]A(t) = A(0)(1 - r)^t[/tex]

[tex]A(t) = 100000(0.945742)^t[/tex]

Apos el siguinte dos meses, hay el mes 6, por eso:

[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]

Habra 71.554 unidades despues de los siguientes dos meses.

Answer:

q = 20

Step-by-step explanation:

q 4

5 = 1

4 x 5 = 20

Answer:

Step-by-step explanation:

Step 1:

Start by setting it up with the divisor 4 on the left side and the dividend 34 on the right side like this:

   4 ⟌ 3 4  

Step 2:

The divisor (4) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:

       0    

   4 ⟌ 3 4  

Step 3:

Multiply the divisor by the result in the previous step (4 x 0 = 0) and write that answer below the dividend.

       0    

   4 ⟌ 3 4  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.

       0    

   4 ⟌ 3 4  

     - 0    

       3    

Step 5:

Move down the 2nd digit of the dividend (4) like this:

       0    

   4 ⟌ 3 4  

     - 0    

       3 4  

Step 6:

The divisor (4) goes into the bottom number (34), 8 time(s). Therefore, put 8 on top:

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

Step 7:

Multiply the divisor by the result in the previous step (4 x 8 = 32) and write that answer at the bottom:

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

      3 2  

Step 8:

Subtract the result in the previous step from the number written above it. (34 - 32 = 2) and write the answer at the bottom.

       0 8  

   4 ⟌ 3 4  

     - 0    

       3 4  

     - 3 2  

         2  

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 34 divided by 4 calculated using Long Division is:

8

2 Remainder

Answer:

4 remainders

Step-by-step explanation:

Here we will show you step-by-step with detailed explanation how to calculate 4 divided by 34 using long division.

Before you continue, note that in the problem 4 divided by 34, the numbers are defined as follows:

4 = dividend

34 = divisor

Step 1:

Start by setting it up with the divisor 34 on the left side and the dividend 4 on the right side like this:

 3 4 ⟌ 4    

Step 2:

The divisor (34) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

 3 4 ⟌ 4    

Step 3:

Multiply the divisor by the result in the previous step (34 x 0 = 0) and write that answer below the dividend.

       0    

 3 4 ⟌ 4    

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

 3 4 ⟌ 4    

     - 0    

       4    

You are done.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 4 divided by 34 calculated using Long Division is:

0

4 Remainder
