Answer:

24″ width, 12″ length. Let the length be X inches, then width is 2X inches, giving perimeter 2(X+2X)=6X inches, which is 72″. hence X, length =12″, and width 24″. The perimeter of a rectangle is 64 m.

Answer:

36

Step-by-step explanation:

72 divided by four because its perimeter and you get 18 on each side since the width is double then you would do 18x2 and get 36.

Draw a line segment 7cm long .
White raven [17]

Answer:

The line segment 7 cm long is shown below.

Step-by-step explanation:

First we draw a line line segment whose length is 7 cm long. Then we divide the line in small parts.

The length of each part is 1 cm.

Six points on the line segment divides the line in 7 equal parts and length of each part is 1 cm.

From the figure it is noticed that we have total 7 small parts and length of each part is 1 cm. So length of 7 parts is

7\times 1=7

Hence the total length of line is 7 cm.

Identify the factors of x2 − 4x − 21. (x − 7)(x 3) (x 7)(x − 3) (x 21)(x − 1) (x − 21)(x 1)
Tanzania [10]

The factors of the quadratic expression x² - 4x - 21 is <u>(x - 7)(x + 3)</u>, making the <u>first option</u> the right choice.

A quadratic expression is of the form ax² + bx + c, which can be factorized using the mid-term factorization method, where b is shown as the sum or difference of two such numbers, whose product is equal to the product of a and c.

In the question, we are asked to factorize the quadratic expression, x² - 4x - 21.

In the given expression, a = 1, b = -4, and c = -21.

Thus, ac = -21.

The numbers having a product 21 are:

1*21 = 21,

3*7 = 21.

Since, 3 - 7 = -4 (That is b), we break b into 3 and -7.

Thus, the expression can now be shown as:

x² - 4x - 21

= x² + (3 - 7)x - 21

= x² + 3x - 7x - 21

= x(x + 3) - 7(x + 3) {By taking common}

= (x - 7)(x + 3) {By taking common}.

Thus, the factors of the quadratic expression x² - 4x - 21 is <u>(x - 7)(x + 3)</u>, making the <u>first option</u> the right choice.
