The coordinates of the vertices of quadrilateral ABCD are A(-5, 1), B(-2,5), C(5, 3),
sladkih [1.3K]

Step-by-step explanation:

To calculate a slope, we need to apply: m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Applying formula to each slope:

m_{AB}=\frac{5-1}{-2-(-5)} = \frac{4}{3}  \\m_{BC}=\frac{3-5}{5-(-2)} =\frac{-2}{7}\\m_{CD}=\frac{-1-3}{2-5}=\frac{-4}{-3} =\frac{4}{3}

So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>

A rectangle has an area of 84 square feet. the length is twice the width. draw a rectangle and draw a line dividing it in two to
algol13

The width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.

<h3>How to determine the dimensions</h3>

The formula for determining the area of a rectangle is expressed as;

Area = width × length

Given that;

  • Area = 84 square feet
  • length = 2w

Let's substitute into the formula

84 = w(2w)

84 = 2w²

Divide both sides by 2

84/ 2 = w²

42 = w²

Take square root of both sides

w = √42

w = 6.4 feet

Length = 2w = 2 × 6. 4 = 12. 96 meters

Thus, the width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.
