Because the two lines parallel, so we have x+40=3x-10
Or 3x-x=40+10
And 2x=50, so we obtain x=25
That is the answer

A police officer seals off the scene of an accident using a roll of yellow tape that is 272 feet long. What dimensions should be

klasskru [66]

Answer:

68 feet square

Step-by-step explanation:

The rectangle with the maximum area for a given perimeter is a square. The perimeter of a square is 4 times the side length, so the side length of the square area will be ...

(272 ft)/4 = 68 ft

_____

More formally ...

You can let x represent the length of one side. Then the length of the other side for the given perimeter will be 136 -x, and the area will be the product ...

area = x(136 -x)

The area function is a quadratic with zeros at x=0 and x=136. The vertex (maximum area) will be at the value of x that is on the line of symmetry between these points, at their midpoint: x = (0 +136)/2 = 68. This value of x makes the rectangle a square.

Factor (3c–5)^2–16c^2

melisa1 [442]

Here is your answer

${(3c - 5)}^{2} - {16c}^{2}$

$= {(3c - 5)}^{2} - {(4c)}^{2}$

$using \: identity \\ {a}^{2} - {b}^{2} = (a + b)(a - b)$

$(3c - 5 + 4c)(3c - 5 - 4c)$

$(7c - 5)( - c - 5)$

Describe the three base materials in soil in terms of porosity and permeability.

777dan777 [17]

Porosity:

Porosity is an intrinsic property of every material.
It refers to the amount of empty space within a given material.
In a soil or rock the porosity (empty space) exists between the grains of minerals.
The amount of water a material can hold is directly related to the porosity since water will try and fill the empty spaces in a material.
We measure porosity by the percentage of empty space that exists within a particular porous media.

Permeability:

Permeability is another intrinsic property of all materials and is closely related to porosity.
Permeability refers to how connected pore spaces are to one another.
If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them.
