What is -2x-18=-4x-6<br> need step by step

Kazeer [188]

Answer:

$\boxed {x = 6}$

Step-by-step explanation:

Solve for the value of $x$ :

$-2x - 18 = -4x - 6$

-Take $4x$ and add it to $-2x$ :

$-2x - 18 + 4x = -4x + 4x - 6$

$2x - 18 = -6$

-Add both sides by $18$ :

$2x - 18 + 18 = -6 + 18$

$2x = 12$

-Divide both sides by $2$ :

$\frac{2x}{2} = \frac{12}{2}$

$\boxed {x = 6}$

Thus, the value of $x$ is $6$ .

A rectangle in the xy-coordinate plane is formed by the points (1,−4), (1,6), (3,−4), and (3,6). What is the perimeter of this r

Airida [17]

Answer:

Perimeter of the rectangle= $20+2\sqrt{104}$

Step-by-step explanation:

The perimeter of the rectangle with the given coordinates is the sum of its all four sides:

Let the points be A(1,-4), B(1,6), C(3,-4) and D(3,6)

Finding the sides of the rectangle using the Distance formula:

AB=

$\sqrt{(1-1)^2+(6-(-4))^2} \\\\=\sqrt{0+10^2} \\\\=\sqrt{100}\\\\ =10$

BC

$=\sqrt{(3-1)^2+(-4-6)^2} \\\\=\sqrt{2^2+(-10)^2}\\\\ =\sqrt{4+100} \\\\=\sqrt{104}$

CD=

$\sqrt{(3-3)^2+(6-(-4))^2} \\\\=\sqrt{0+10^2} \\\\=\sqrt{100} \\\\=10$

AD=

$\sqrt{(3-1)^2+(6-(-4))^2} \\\\=\sqrt{2^2+10^2} \\\\=\sqrt{4+100}\\\\ =\sqrt{104}$

Perimeter of the rectangle=AB+BC+CD+AD

= $10+\sqrt{104}+ 10+\sqrt{104}$

Perimeter of the rectangle= $20+2\sqrt{104}$

Standing in your tree house, 50 feet off the ground, you look down at a 60Â° angle and notice a frisbee. approximately how many

andrew11 [14]

Draw a diagram
assuming you are directly over the base of the tree

we need to find the ratio between the adjacent angle and oposite angle

adjacent angle is the disatnce from frisbee to base of tree
oposite angle is 50ft

so
tan=oposite/adjacent
tan(60°)=50/?
?tan(60°)=50
?=50/tan(60°)
use your calculator
?≈28.8675
so about 29ft away from the base of the tree is the frisbee
