Could 13.5 cm, 8.0 cm, and 3.5 cm be the side lengths of a triangle?
Sergio039 [100]
The answer is no, it couldn't be because the side lengths do not adhere to the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side

WICH EQUATION CAN BE USED TO FIND THE AREA OF THE RECTANGLE
allsm [11]

Answer:

A = L x W

Step-by-step explanation:

<em>Because the equation of a rectangle is understood the best way to help you understand the equation of l*w is to break down the definiton of a rectangle.</em>

Defining a rectangle:

The rectangle is a quadrillateral with two parallel sets of sides which are perpendicular to each other.

Understanding it:

Now let's look at a rectangle

Let's say the length is 5 units and the width is 10 units.

To find that meat in between we understand that 5 units of length extends through all 10 units of the width. This means 5 is carried out for 10 units meaning that 5x10 is the area of the Rectangle. As such the area would be 50

So the area of a rectangle is its length times its width

What values of x and y satisfy -13/3 x-2 y=7 and 3x+2/5 y=5 simultaneously?
Aloiza [94]
Multpiply first equation by 3 and second by 5 to clear nasty faractions

-13x-6y=21
15x+2y=25

now see which ones we can clear
we can clear y
multiply second equation by 3 and add to the first equation

-13x-6y=21
<u>45x+6y=75 +</u>
32x+0y=96

32x=96
divide both sides by 32
x=3

sub back
15x+2y=25
15(3)+2y=25
45+2y=25
minus 45 from both sides
2y=-20
divide both sides by 2
y=-10

x=3
y=-10
(3,-10)
