The polynomial in a standard form that represents the perimeter of the quadrilateral is [tex]22x-3[/tex].

Important information:

We need to find the polynomial in a standard form that represents the perimeter of the quadrilateral.

The perimeter of the quadrilateral is the sum of all of its sides.

[tex]\text{Perimeter}=3x-2+2x+12x+1+5x-2[/tex]

[tex]\text{Perimeter}=22x-3[/tex]

Therefore, the polynomial in a standard form that represents the perimeter of the quadrilateral is [tex]22x-3[/tex].

Answer:

970 cm

Step-by-step explanation:

Given that:

Size of brick :

25cm × 16cm × 10cm

Number of bricks = 4700

Dimension of wall = 20 m long × 20 cm wide

Let the height = h

Hence, dimension of wall (length and height)

2000 cm × h

Dimension of window = 2m × 1.5m = 200cm × 150cm

Number of windows = 2

Total area covered by windows = 2 * (L * B)

= 2(200 * 150) = 60,000cm

Brick = (25 * 16) * 4700 = 1, 880, 000 cm ( length and height)

Wall = 2000 * height - 60,000 = 1880000

2000height - 60,000 = 1880000

2000height = 1880000 + 60,000

2000height = 1940000

Height = 1940000 / 2000

Height of wall = 970 cm

Answer:

89

Step-by-step explanation:

There are only 30 pages but last page number is 89.

The last page of the book would be with the number 89. For details, check the calculations below.

The number system is characterized as the arrangement or sequence in which the numbers are arranged in a mathematical order beginning from 0 in whole numbers.

In the given situation,

We know that,

Total pages available in the book = 30

And every third page is omitted from the book due to misprinting of the page numbers.

If we divided 90/3 = 30 pages are there. Hence, the last page would be 89 itself.

Thus, the above response is correct.

Answer:

n^2/4

Step-by-step explanation:

If n is the number, squared is n^2

Quotient if this number and four is

n^2/4

The quotient of a number squared and four will be n² / 4.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

The square of a number is the multiplication of that number with itself.

Let the number be n.

Then the square of the number n will be given as,

⇒ n²

The quotient of a number squared and four will be given as,

⇒ n² / 4

Thus, the quotient of a number squared and four will be n² / 4.

B) the sum is linear and the product is quadratic

D) the sum has one y-intercept and the product has two x-intercepts

The sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product

Two or more expressions with an Equal sign is called as Equation.

We need to find the statements which correctly compare the sum and product

The given statements are

1. Both functions have a constant rate of change.

2. The sum is linear and the product is quadratic.

3. The x-intercepts are the same.

4. The sum has one y-intercept and the product has two x-intercepts.

5. Both functions decrease for x > 2

A linear function simply means a function that represents a straight line on the coordinate plane.

In this case, the sum is linear and the product is quadratic while the sum has one y-intercept and the product has two x-intercepts.

Hence, the sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product

Answer:

22/3

Step-by-step explanation:

First, I multiplied 7 and 3 because 7 is the whole number and 3 is the denominator of the fraction.

7*3=21

Then, I added 21 to 1 because 1 is the numerator in the fraction.

21+1=22

Finally, I made it 22/3 because the denominator of the fraction is 3.

So, your final answer is 22/3.

[tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as 22/3.

Given is to write 7 1/3 as a improper fraction.

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. We can write that for a fraction {x/y} to be improper, the following conditions should be fulfilled -

{x} > {y}

or

{x} ≥ {y}

We can write 7 1/3 as a improper fraction as -

[tex]$7\frac{1}{3}[/tex] = [tex](3\times7+1)/3[/tex] = [tex]$\frac{22}{3}[/tex]

Therefore, [tex]$7\frac{1}{3}[/tex] as a improper fraction can be written as [tex]$\frac{22}{3}[/tex].
