Hello from MrBillDoesMath!

Answer:

x = 12

Discussion:

From the diagram, the two triangles appear to be similiar. Then

28/7 =  (6x + 28)  /25

as the ratio of corresponding parts of similar triangle are  the same.

28/7 = (6x +28)/25           => simplify. 28/7 = 4

4 = (6x + 28)/25                => multiply both sides by 25

4*25 = 6x + 28                  => simplify, 4 * 25 = 100

100 = 6x + 28                    => subtract 28 from both sides

100 -28 = 6x                      => simplify. 100 - 28 - 72

72 = 6x                               => divide both sides by 6

72/6 = 12 = x

Thank you,

MrB

A rectangle has a length that is 7 inches less that twice it's width. The area of the rectangle is 72 square inches. Write an eq
Nitella [24]

Answer: 2x^2-7x=72 , where  x= width of the rectangle ( in inches).

Step-by-step explanation:

Let x= width of the rectangle ( in inches).

Then its length =  2x-7 ( in inches).

Area of rectangle = Length × width

= (2x-7) × (x)

= 2x × x -7 ×x

= 2x²-7x

The area of the rectangle is 72 square inches.

\Rightarrow\ 2x^2-7x=72

Hence, the equation that represents the given situation :

2x^2-7x=72

Which step is the same when constructing an inscribed square and an inscribed regular hexagon?
Colt1911 [192]

After the construction of a circle, we have to "Set the compass to the radius of the circle" so, option C is correct.

<h3>What is a regular hexagon?</h3>

A regular hexagon is defined as a closed shape consisting of six equal sides and six equal angles. The sum of the measure of angles of a regular hexagon is 120 degrees.

Steps to create an inscribed hexagon:

1: The structure needs to adjust the box thickness towards that radius.

2: Afterward moves around the outside of the circular path to just produce the 6 vertices of that similar hexagon.

"Set the compass to the radius of the circle" so, option C is correct.

Thus the above answer is correct.
