Answer:

  42

Step-by-step explanation:

For the proportion ...

  \dfrac{2}{7}=\dfrac{12}{x}

Form the "cross products" by multiplying both sides of the equation by 7x (the product of the denominators. This gives you ...

  7x\cdot\dfrac{2}{7}=7x\cdot\dfrac{12}{x}\\\\2\cdot x=7\cdot 12\qquad\text{each numerator $\times$ the opposite denominator}\\\\2x=84

After you have formed the "cross products", divide by the coefficient of x:

  x = 84/2 = 42

The value of x is 42.

a rectangular garden is fenced on alls ides with 256 feet fencing. the garden is 8 feet longer than it is wide
pickupchik [31]

The length and width of the rectangular garden is estimated as-

  • Length = 68 ft
  • width= 60 ft
<h3>How to calculate perimeter of the rectangle?</h3>

A rectangle's perimeter is the total length and distance of its border across all sides. The perimeter of a rectangular box is a linear measurement that is expressed in meters, feet, cm, or yards. Let us first examine the two primary characteristics of a rectangle.

  • A rectangle's four angles are all 90°.
  • A rectangle's opposite sides are of equal length.

The perimeter of the rectangle is given as-

Perimeter = 2(length + width)

perimeter= 256

Let the width of the rectangle be x.

Length is 8 feet longer than width, Thus,

length = x+8

Substitute the values in the formula of perimeter;

256 = 2( x+ 8+ x)

256 = 2( 2x + 8)

128= 2x + 8

120= 2x

x=60

Thus, width = 60 ft.

Length = 60 + 8 = 68 ft.

Therefore, the length and width of the rectangular garden is estimated.
