Solve AND graph the inequality below. −2x−4≤11
ankoles [38]

Answer:

x\ge \:-\frac{15}{2}

The graph of the inequality is attached below.

Step-by-step explanation:

Given the inequality

-2x-4\le 11

\mathrm{Add\:}4\mathrm{\:to\:both\:sides}

-2x-4+4\le \:11+4

-2x\le \:15

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}

\left(-2x\right)\left(-1\right)\ge \:15\left(-1\right)

2x\ge \:-15

\mathrm{Divide\:both\:sides\:by\:}2

\frac{2x}{2}\ge \frac{-15}{2}

x\ge \:-\frac{15}{2}

The graph of the inequality is attached below.

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.
