What is the most precise name for a quadrilateral with the following vertices:

pashok25 [27]

<h2>Therefore it is a parallelogram.</h2>

Step-by-step explanation:

Given the vertices of the quadrilateral are A(2,3) , B(7,2), C(6,-1) and D(1,0)

The length of AB is $=\sqrt{(2-7)^2+(3-2)^2}$ $=\sqrt{26}$ units

The length of BC is $=\sqrt{(7-6)^2+(2+1)^2}$ $=\sqrt{10}$ units

The length of CD is $=\sqrt{(6-1)^2+(-1-0)^2}$ $=\sqrt{26}$ units

The length of DA is $=\sqrt{(1-2)^2+(0-3)^2}$ $=\sqrt{10}$ units

The length of AC is $=\sqrt{(2-6)^2+(3+1)^2}$ $=4\sqrt{2}$ units

The length of BD is $=\sqrt{(7-1)^2+(2-0)^2}$ = $2\sqrt{10}$ units

Here length of AB = length of CD ,

length of BC= length of DA and

length of AC ≠ length of BD

In this quadrilateral, the opposite sides are equal but the diagonals are not equal

Therefore it is a parallelogram.

Answer:

$(-\frac{3}{7}, 0)$ -- x intercept

$(0,3)$ -- y intercept

Step-by-step explanation:

Given

$y = 7x + 3$

Required

Determine the x and y intercept

For x intercept.

Set $y = 0$

So, we have:

$y = 7x + 3$

$0 = 7x + 3$

Collect Like Terms

$7x = -3$

Make x the subject

$x = -\frac{3}{7}$

Hence, the x intercept is: $(-\frac{3}{7}, 0)$

For the y intercept;

Set $x = 0$

So, we have:

$y = 7x + 3$

$y = 7*0 + 3$

$y = 0 + 3$

$y = 3$

Hence, the y intercept is: $(0,3)$

The length of a rectangle is 4 yd less than three times the width, and the area of the rectangle is 55 ya? Find the dimensions o

inysia [295]

Answer:

length = 11 yard

width = 5 yard

Step-by-step explanation:

Area of a rectangle = L W

where A = 55 yard

L = 3W - 4

find: Length

width

solution:

A = L W

55 = (3W - 4) W

55 = 3W² - 4W

3W² - 4W - 55 = 0

use quadratic equation to solve for W:

W = <u> - (-4) ± √(-4)² - 4(3)-55 </u>

2(3)

W = 5, W = -11/3

substitute W=5 to equation L = 3W - 4 to solve for L

L = 3W - 4

L = 3(5) - 4

L = 15 - 4

L = 11

therefore, the dimensions of a rectangle:

length = 11 yard

width = 5 yard
