Can you please help solve this division problem. If you explain I will give Brainly

Step-by-step explanation:

We khow the sum and the product of the zeroes of this quadratic polynomial

Here is a trick :

when we khow the sum S and the product P ofvtwo numbers we can find them by solving :

x²-Sx+p=0

here S= -8 and P=12

so:

x²+8x+12=0

Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12

Δ= 8²-4*12 =16

the zeros are:

(-8-4)/2= -6

(-8+4)/2 = -2

verify:

-6+(-2)= -8

-2*(-6)= 12

now the polynomial quadratic is:

(x+6)(x+2)

Answer: 4032 squared feet

Step-by-step explanation:

1. Identify the figure. Rectangular Pyramid

2. Find the area of the four triangle faces.  1/2*47*32 = 752. Then, 752*4 = 3008.

3. Find the area of the rectangular base. 32*32 = 1024

4. Add the areas together, 3008+1024 = 4032

Answer:

12.6 hp

Step-by-step explanation:

output of motor = 85.4% of input of motor.

Given that motor delivers 10.75 hp, it means output of motor is 10.75hp

Using both the given conditions

10.75 = 85.4% of input of motor

=> 10.75 = 85.4/100  * input of motor

=> input of motor = 10.75*100/85.4 = 1075/85.5 hp = 12.57 hp.

Input of motor rounded to 1 decimal place = 12.6 hp

Answer:

you have to divivide both number to find the height=57.1

Step-by-step explanation:

Step-by-step explanation:

Perimeter = 2×(Height × Base)

269.4 = 2(Height × 77.6)

269.4 = 155.2 × 2Height

2Height = 114.2

Height = 57.1 miles

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

[tex]\frac{15}{x} = \frac{15+5}{8+x}[/tex]

[tex]\frac{15}{x} = \frac{20}{8+x}[/tex]

Cross Multiply

[tex]15 * (8 + x) = 20 * x[/tex]

Open bracket

[tex]15*8 + 15 * x = 20 * x[/tex]

[tex]120 + 15x = 20x[/tex]

Subtract 15x from both sides

[tex]120 + 15x -15x= 20x-15x[/tex]

[tex]120 = 20x-15x[/tex]

[tex]120 = 5x[/tex]

Divide both sides by 5

[tex]\frac{120}{5} = \frac{5x}{5}[/tex]

[tex]\frac{120}{5} = x[/tex]

[tex]24 = x[/tex]

[tex]x = 24[/tex]

Hence, the length of the missing segment is 24

Answer:

The answer is option B

f( 5) = - 1

Hope this helps you

Regarding the graph function f(x), it is only F(5) = -1 that is true. Option B is the correct answer.

The slope (m) of the graph is

m = (4 - 0) / (0 - 4)

m = -1

From general linear equation:  y = mx + c

The equation of the function is;

y = -x + 4

f(x) = -x + 4

Let us check all the options one by one.

If x = 0,

F(0) = 4  This is not true

If x = 5

F(5) = -5 + 4

F(5) = -1  This is true.

Therefore, regarding the graph function f(x), it is only F(5) = -1 that is true. Option B is the correct answer.

Answer: 51

Step-by-step explanation:

Answer:

86.82%

Step-by-step explanation:

A nautical mile = 6,174 feet.

Statute mile =5,360 feet

The percentage of a statute mile to a nautical mile is calculated as:

5360/6174 × 100

= 0.8681567865 × 100

= 86.81567865%

Approximately to the nearest hundredth = 86.82%

Therefore, the percent of a statute mile that is a nautical mile rounded to the nearest hundredth is 86.82%

Answer:

The length of the missing segment is 44

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

[tex]\frac{20}{x} = \frac{10+20}{22+x}[/tex]

[tex]\frac{20}{x} = \frac{30}{22+x}[/tex]

Cross Multiply

[tex]20 * (22 + x) = 30 * x[/tex]

Open bracket

[tex]20 * 22 + 20 * x = 30 * x[/tex]

[tex]440 + 20x = 30x[/tex]

Subtract 20x from both sides

[tex]440 + 20x - 20x= 30x- 20x[/tex]

[tex]440 = 30x- 20x[/tex]

[tex]440 = 10x[/tex]

Divide both sides by 10

[tex]\frac{440}{10} = \frac{10x}{10}[/tex]

[tex]\frac{440}{10} = x[/tex]

[tex]44 = x[/tex]

[tex]x = 44[/tex]

Hence, the length of the missing segment is 44

Answer:  (-x, y-7)

Step-by-step explanation:

A reflection across the y-axis changes the sign of the x-value.

(x, y)   →  (-x, y)

Shifting down 7 units subtracts 7 from the y-value.

(-x, y)   →   (-x, y-7)

Answer: g> -1

Step-by-step explanation:

The given inequality is [tex]g+6>5\ .[/tex]

To solve the above inequality for g, we just need to remove 6 from the left side by subtracting it, for that we have to subtract 6 from both the sides, we get

[tex]g+6-6>5-6\\\\\Rightarrow\ g>-1[/tex]

i.e. The value of g is strictly greater than -1.

Hence, the correct answer is g> -1.

Answer:

  21h miles

Step-by-step explanation:

The appropriate relation is ...

  distance = speed · time

__

We are given that ...

  biking time = h

  walking time = 2h

  running time = (1/4)(2h) = h/2

The total distance traveled is ...

  total distance = biking distance + walking distance + running distance

     = (10)(h) +(3)(2h) +(10)(h/2)

     = 10h + 6h + 5h

  total distance = 21h . . . miles

Answer:

21h miles

Step-by-step explanation:

The appropriate relation is ...

 distance = speed · time

__

We are given that ...

 biking time = h

 walking time = 2h

 running time = (1/4)(2h) = h/2

The total distance traveled is ...

 total distance = biking distance + walking distance + running distance

    = (10)(h) +(3)(2h) +(10)(h/2)

    = 10h + 6h + 5h

 total distance = 21h . . . miles:

Answer:

[tex]\frac{x^{\frac{1}{2}}}{y^{\frac{1}{4}}z^2}[/tex]

Step-by-step explanation:

Given

[tex]x^{\frac{1}{2}}y^{-\frac{1}{4}}z^{-2}[/tex]

Required

Find the equivalent

To find the equivalent of the given expression; we have to apply laws of indices;

As a law;

[tex]a^{-m} = \frac{1}{a^m}[/tex]

So; the expression [tex]x^{\frac{1}{2}}y^{-\frac{1}{4}}z^{-2}[/tex] becomes

[tex]x^{\frac{1}{2}}*\frac{1}{y^{\frac{1}{4}}}*\frac{1}{z^2}[/tex]

This is further simplified to

[tex]x^{\frac{1}{2}}*\frac{1}{y^{\frac{1}{4}} * z^2}[/tex]

[tex]x^{\frac{1}{2}}*\frac{1}{y^{\frac{1}{4}}z^2}[/tex]

Combine to form a single fraction

[tex]\frac{x^{\frac{1}{2}}*1}{y^{\frac{1}{4}}z^2}[/tex]

Multiply numerator

[tex]\frac{x^{\frac{1}{2}}}{y^{\frac{1}{4}}z^2}[/tex]

The expression can not be further simplified

Hence [tex]x^{\frac{1}{2}}y^{-\frac{1}{4}}z^{-2}[/tex] is equivalent to [tex]\frac{x^{\frac{1}{2}}}{y^{\frac{1}{4}}z^2}[/tex]

Answer:

The answer is (a+c) + 7

Since addition is associative a + ( C + 7) can also be written as (a+c) + 7

Hope this helps you

Answer:

(a+c)+7

Step-by-step explanation: This method is called associative property.

On addition changing the order brings no change to the answer. For example:- 2+3=3+2. but don't confuse this with multiplication. For example, if the question was a(c+7), then you are supposed to multiply c, + and 7 by a.

Answer:

no the ratios of corresponding sides are not equal

Step-by-step explanation:

For two rectangles to be considered similar, the ratio of the length of their corresponding sides must be of equal measure.

Let's find out if the 2 given rectangles are similar or not by finding the ratio of the length of their corresponding sides as follows:

3/3 = 1

4/6 = 2/3

Thus, 3/3 ≠ 4/6

The ratio of their corresponding sides are not equal. Therefore, the two rectangles bare not similar.

The answer is: "no the ratios of corresponding sides are not equal".

Answer:

Step-by-step explanation:he correct answer is:

the eighth root of 2 to the fifth power .

Explanation:

What we have is:

Using the rules of exponents, we know that when we divide powers with the same base, we subtract the exponents. The base of each exponent is 2, so we subtract:

7/8 - 1/4

We find a common denominator. The smallest thing that both 8 and 2 will evenly divide into is 8:

7/8 - 2/8 = 5/8

This gives us:

When rewriting rational exponents as radicals, the denominator is the root and the numerator is the power. This means that 8 is the root and 5 is the power, which gives us:

,

or in words, the eighth root of 2 to the fifth power.
