The width of a rectangle is 6 kilometers less than twice its length. if its area is 108 square kilometers, find the dimensions

Art [367]

Hi there!

Answer:
length = 9 kilometres
Width = 12 kilometres

Let's solve this problem step by step!
To find our answer we need to set up and solve an equation.

Let the length of the rectangle be represented by x.
The width of the rectangle can therefore be expressed by 2x - 6.

The area of a rectangle can be found by using the formula:
A = width × length

Plug in the data from the formula
A = x (2x - 6).

Simplify using rainbow technique.
$x(2x - 6) = 2 {x}^{2} - 6x$

Now we've found the simplified expression that expresses the area of the rectangle. Therefore, we can now set up and start solve the equation.

$2 {x}^{2} - 6x = 108$
Subtract 108

$2 {x}^{2} - 6x - 108 = 0$
Divide by 2.

${x}^{2} - 3x - 54$
$(x - 9)(x + 6) = 0$
Rule AB = 0, gives A is 0 or B is 0.

$x - 9 = 0 \\ x = 9 \\ \\ x + 6 = 0 \\ x = - 6$

The length of the rectangle, which was represented by x, must be 9 (since it cannot be a negative number).

Length
$x = 9$
Width
$2x - 6 = 2 \times 9- 6 = 18 - 6 = 12$

Answer:
length = 9 kilometres
Width = 12 kilometres

What is the answer to this question

stiv31 [10]

4(d-8)-5 = 9(d+2)+1

Assuming you're looking for d:

Use Distributive Property for both sides
4d-32-5 = 9d+18+1

Combine like terms
4d-37 = 9d+19

Take all d's to one side & numbers to other
-37-19 = 9d-4d

Simplify
-56 = 5d

Divide both sides by 5
d = -56/5

A helicopter flying 1,600 feet above the ground spots an airplaneflying above. If the horizontal distance between the helicopter

laila [671]

Answer:

10472. 4 ft

Step-by-step explanation:

Let the height of the plane above the helicopter be "h"

We have a right triangle where the side opposite the 71 degree angle = h and the side adjacent to this angle = 3055

So we can use the tangent here

tan (71) = h / 3055 multiply both sides by 3055

3055 * tan (71) = h ≈ 8872.4 ft

So.......the total altitude of the plane is

1600 + 8872.4 =

10472. 4 ft

Find the measure of the angle indicated. ? 82 A) 77° C) 82 B) 75 D) 127°

Naddik [55]

Answer:

c) 82

Step-by-step explanation:

It's 82 degrees because of the opposite interior angle theorem, which means that those two angles are the same, as well as any pair of opposite interior angles.
