find the value of x and y ​

Answer: 84m

Step-by-step explanation:

If one of the perimeters are 2m longer than the other that means on side can be expressed as x and the other expressed as x+2

So the equation for the area is [tex]x^{2} \\[/tex]+2x

Becasue the shaded area has an gap of in it we need to find the area of the gap to find the total area of the square

0.5x3x4=6

114+6

So the total area is 120

So we can use the area equation from before to figure out x

120=[tex]x^{2} \\[/tex]+2x

0=[tex]x^{2} \\[/tex]+2x-120

0=(x-10)(x+12)

Since its a measurement x must equal 10

Now we know that one side is 20m and the other is 22m

So the perimetre must be 84

The first expression (9 - 5) / (4 - 0) is used to determine the slope of the linear function represented in the table.

What is slope of the line?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. where "m" represents a line's slope. So, the slope of a line is tanθ.

From the given table the points are, (0, 5) and (4, 9).

Since, for points [tex](x_1, y_1), (x_2, y_2)[/tex] the slope can be defined as,

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here,

[tex](x_1, y_1)=(0, 5)\\(x_2, y_2)=(4, 9)[/tex]

So, the slope is

[tex]m = \frac{9-5}{4-0}[/tex]

This is the first expression.

Therefore, the first expression (9 - 5) / (4 - 0) is used to determine the slope of the linear function represented in the table.

After converting into a linear equation, we have the equation y = -3x

What is a linear equation?

A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. This indicates that there are no variables in a linear equation with exponents greater than 1. A linear equation's graph almost always takes the shape of a straight line.

Solution Explained:

From the question, we have
x = -1
y = 3
slope (m) = -3

Substituting these values in the equation,

y = mx + c

3 = (-3) x -1 + c

After simplyfing the equation, we get

c = 0

We again substitute the value of m and c in the equation,

y = mx + c

y = -3x + 0

y = -3x

Hence, the linear equation is y = -3x.

The graph of the proportional relationship is (c) A line from (0, 0) going through (38, 34.20) where the x-axis is labeled Weight (in pounds) and the y-axis is labeled Cost (in dollars)

From the question, we have

It costs $20.70 for 23 pounds of laundry and $34.20 for 38 pounds of laundry

This means that

(x, y) = (20.70, 23) and (34.20, 38)

Where

x = Weight and y = Cost

From the question, we understand that

The graph is a proportional graph

This means that the line passes through the origin

So, we have

(x, y) = (0, 0), (20.70, 23) and (34.20, 38)

Remove one of the points

(x, y) = (0, 0) and (34.20, 38)

The approximate area of the regular pentagon is 342cm²

Using the Pythagorean theorem, we can calculate the apothem of the pentagon.

We have then:

a = √(12² - (14.1/2)²)

a = 9.7

Then, the area of the pentagon is given by:

Area = 5 (1/2) x l x a

Where,

L: side of the pentagon

a: apotema

Substituting values:

area = 5(1/2) x 14.1 x 9.7

area = 341.925 cm²

Rounding the nearest whole we have: 342 cm²

Hence, the approximate area of the regular pentagon is 342cm²

We know that coordinates of the point (x,y) after dilation by factor k centered at (a,b) is  (k(x-a) + a , k(y-b) + b)  .

In the question ,

it is given that

the slope of the line p [tex]=[/tex] 3

and the intercept of the line p = (0,2)

So , the equation of the line p is y = 3x + 2 .

So , the coordinates of the point (0,2) after dilation by factor 3 centered at (0,0) is (3(0 - 0) + 0 , 3(5 - 0) + 0)

Area of triangle equation:

Find the value of h, using given values:

Use Pythagorean and find the missing side s of the triangle:

Find the perimeter of this isosceles triangle:

The perimeter of the triangle is 70 ft.

A triangle is a polygon with 3 sides.

Given that, the area of the triangle is 168 square feet.

The formula for the area of a triangle with base b and height h is:

A = (1/2)×bh

Substitute A = 168 and b = 14 into the equation:

168= (1/2)×(14)h

168/14 = (1/2)h

12 = (1/2)h

12×2 = h

24 = h

Hence, the height of the triangle is 24 ft.

Let the length of the slant side of the triangle be s.

Use the Pythagorean theorem to find the value of s:

s² = b² + h²

Substitute b= 14 and h = 24 into the equation:

s² = 14² + 24²

s² = 196 + 576

s² = 772

s = √772

s ≈ 28

The length of both slant sides of the triangle is the same, therefore, the perimeter of the triangle is given by:

P = 14 + 28 +28

P = 70

The term prime factorization refers to any number represented as the product of its prime factors.

For instance, the prime factors that make up the number 60 are listed as follows:

60=2×3×2×2×5

The idea behind prime factorization is to divide the provided whole numbers into their prime factors in order to find the largest common factor and least common multiple of each number.

Procedures for using prime factorization to find the greatest common factor (G.C.F.)

The given numbers should be written as their prime factors.

To find the G.C.F., multiply each of the given numbers by the product of the discovered common factors.

For instance, using the formula below, one may get the largest or greatest common factor between the values 50 and 20.

50 = 2 x 5 x 5

20 = 2 x 2 x 5

The highest common factor is found by multiplying the common prime factors of 50 and 20.

G.C.F = 2 x 5

The greatest common factor of the supplied numbers can then be computed using prime factorization.

Following these steps will help you use prime factorization to find the LCM:

In the form of their prime factors, write the given numbers.

Take the product of the numbers' rare prime factors and discovered common prime factors.

For instance, using prime factorization, the least common multiple of the numbers 50 and 20 can be calculated as follows:

Separately write the prime factors of 50 and 20.

50 = 2 x 5 x 5

20 = 2 x 2 x 5

Multiply the resulting common prime factors (2 and 5) with the remaining uncommon prime factors (2 and 5) to find the least common divisor.

L.C.M = 2 x 2 x 5 x 5

In this way, we can take advantage of prime factorization to compute the least common multiple of a given number.

The amount of water added by the pool maintenance is:

Amount of water added = 90% of 660,000 - 63% of 660,000
