Answer:
6 cups
Step-by-step explanation:
12×5=60(cookies in 4 cups of flour)
90-60=30(30 cookies in 2 cups
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
3.5+8>13.5 Is not correct.
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
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)
