PLEASE HELP ME I DO NOT UNDERSTAND WHAT TO DO COULD SOMEONE HELP ME PLEASE THANK YOU I REALLY APPRECIATE IT

a.) A flat pattern that could be folded to make a 3-dimensional figure is called a "net." You can draw one for Tyler's bench by picking any surface of that rectangular prism and making a drawing of it. At any edge you choose, you can add the adjacent surface to your drawing. Keep doing this until all 6 surfaces are shown in their correct relationship to adjacent surfaces. An example is attached. (This is not the only way the net can be drawn.)
Interior lines of the net can be solid or dashed as you wish. I have shown some of them dashed so as to better illustrate how the area can be computed.
b.) The area of this figure represents the surface area of the rectangular prism. The dimensions of each surface will be 1×1.5, 1×5, or 1.5×5. There are two surfaces with each pair of dimensions. (Perhaps you can find each of these rectangles on the net diagram. Ones with the same dimensions are opposite faces of the rectangular prism.) We can add up the areas of the smaller rectangles to find the total, or we can take advantage of the drawing and divide the area into a smaller number of larger chunks that may make the computation easier.
For example, the rectangle AI that is shaded red is 5×4 in size, for a total of 20 ft². The rectangle KN that is shaded green is 8×1 in size, for a total of 8 ft². Then the total amount of cloth Tyler needs to reupholster his bench is
... 20 ft² + 8 ft² = 28 ft²

, you have to take the third root of both sides:
![\sqrt[3]{x^{3}} = \sqrt[3]{1}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%5E%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B1%7D%20)
But that won't help you with understanding the problem. It is better to write
as a product of 2 polynomials:
From this we know, that

If you had meant,, then the simplest form of this fraction would be - 
Divide both parts of the fraction by 4, and you getthe simplest form of the fraction.
Finding out the simplest form of a given fraction is nothing else than cancelation.
Flop it, you have with you -
Flop the simplest form of the previous fraction, that's
If you had meant, then this will certainly be of any use to you.
HOW TO UNDERSTAND THAT THE FRACTION IS IN ITS SIMPLEST FORM?
Maybe, you are just simplifying and simplifying...but you don't even know when to stop. You can understand whether a fraction is in its simplest form or not by seeing that the numerator and the denominator have a common factor to divide it by, or not.
For instance, consider the case here - or <span>. We can't divide it any further. So, we know that it is in its simplest form.

L O N G Process:
Well, if you want to divide it by the smallest common factor to its larger, then --

1) Divided by 2 =
or 
2) Next, also by 2 = or
That took much longer, right.<span> So, it is more preferable to divide the fraction by the possible largest common factor, you can guess of.</span>
