Answer:

Area = 20 units²

Step-by-step explanation:

<em>Let A(-8,-2), B(-3,-2), C(-3,-6) and D(-8,-6) so that the rectangle becomes ABCD.</em>

=> <u><em>Since it's a rectangle it will have two opposite sides equal.</em></u>

<em>So, let's find the length of any two sides (as length and width) by Distance Formula.</em>

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

<u><em>Side AB:</em></u>

|AB| = \sqrt{(-3+8)^2+(-2+2)^2}

|AB| = \sqrt{5^2}

|AB| = 5

<u><em>Side BC:</em></u>

|BC| = \sqrt{(-3+3)^2+(-6+2)^2}

|BC| = \sqrt{16}

|BC| = 4

<u><em>Now, Area:</em></u>

Area of the rectangle = Length * Width

Area = 4 * 5

Area = 20 units²

Find the ratio of the areas.
pshichka [43]

Answer:

  3 -2√2

Step-by-step explanation:

For a regular octagon of side length s, the "flat-to-flat" dimension across the center is s(1+√2). The flat-to-flat dimension of the shaded center octagon is simply s. The ratio of areas is the square of the ratio of linear dimensions, so we have ...

  small area / large area = (1/(1+√2))^2 = 1/(3+2√2)

  small area/large area = 3 -2√2

_____

The attachment shows octagons after the fashion described here. The side length of the larger one is 2 units. The numbers inside are the areas. They have the ratio shown above.

zaharov [31]
Hello there!

4 pencils . 4/9 of an hour = 4/9 of 60 minutes = 4/9 * 60 = 80/3 minutes
x pencils = ? . one hour = 60 minutes14 * 60 = 80/3 * x       /*3
14 * 60 * 3 = 80 * x
80 * x = 2520            /80
x = 2520 / 80
x = 31.5 pencilsThe result would be 32 pencils in one hour.

Hope I helped!

galben [10]

Answer:

14 ft

Step-by-step explanation:

Let x represent the number of segments of the divided wood beam

Let y represent the total length of the wood beam.

Given that each segment measures 3.5, the equation to express this scenario is given as

y = 3.5x

Thus, to find the length of the wood beam, substitute x = 4 into the equation.

We would have:

y = 3.5(4)

y = 14

Length of the wood beam = 14 ft
