Given:
A rectangle has a length of 8 and a width of 4.
Four equal rectangles are drawn within that rectangle, creating the longest lengths possible for the rectangles.
To find:
The sum of the perimeters of two of these equal rectangles.
Solution:
We have to draw 2 lines which are bisecting the length and width respectively, to divide a rectangle in 4 equal parts with longest lengths.
Half of length 8 = 4
Half of width 4 = 2
It means each rectangle have a length of 4 and a width of 2.
Perimeter of a rectangle is
So, perimeter of each equal rectangle is 12 units.
Sum of the perimeters of two of these equal rectangles is
Therefore, sum of the perimeters of two of these equal rectangles is 24.
Area = length * width
241.2 = 15 * width
Width = 241.2/15 = 16.08 meters
Perimeter = 2*length + 2*width = 62.16 meters
Answer:
Hi there I was just working on this question on UsaTestPrep and idk if the answer is really correct but here: C: reflection then rotation.
Step-by-step explanation:
Extra Info:
Dilation is when the shape changes in size, which doesn't happen.
Translation is when it just moves across. It may look like that is happening here, but I'll explain.
The triangle is first reflected along the line . Imaging putting a mirror on the x=0 line (the y axis, basically), and you'd see 1 to 2.
Then, it is rotated around the point . Get a bit of tracing paper, draw over 2, and then, holding the tracing paper down at (works well with a pencil), rotate it round and you will find it fits perfectly over 3.
Also is this the diagram?
An infinite series contains an infinite amount if values within a set S({}. A finite series contains a certain am0unt of values (for example, the numbers from 1 to 10)
The first one is a finite set since it has a known amount of values. This can be seen as a tangible set. The second set has an unknown end. This makes it intangible.
Answer:
(2x - 1)(5x - 2)
Step-by-step explanation:
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 10 × 2 = 20 and sum = - 9
The factors are - 5 and - 4
Split the middle term using these factors
10x² - 5x - 4x + 2 (factor the first/second and third/fourth terms by grouping )
= 5x(2x - 1) - 2(2x - 1) ← factor out (2x - 1)
= (2x - 1)(5x - 2)
