A piece of rectangular sheet metal is 20 inches wide. Its is to be made into a rain gutter by turning up the edges to form paral
vivado [14]
Turning up the edges of the sheet metal will result in the 20 inches of metal being divided into x inches of the first side, then the unknown width of the gutter (let's call it "y") and then again x inches for the second side.

 As a picture: x|______|x/y

 As a formula: 20 = x + y + x = 2x + y

Resolving this to y we get: 20 - 2x = y

and switching it around: y = 20 - 2x,

Now for part b) of your question:
The area of the gutter's cross-section is its width (y) multiplied with its height (x).

A(x,y) = x * y
If we use our result from a) to eliminate y then we can see that
A(x) = x * y = x * (20-2x) = 20x-2x^2
So I'd say that the answer to part b) should be: A(x) = 20x - 2x^2

Please include an explanation.
Phantasy [73]

Answer:

y = 120 ( x - 1/2 ) ( x + 2 )

Step-by-step explanation:

As you can see in every parenthesis there is a coefficient in front of every x term. We do not want them do be there. So we ll eliminate them.

In other words we will factor out from inside each parenthesis the coefficient. So:

y =  - 3(4 - 8x)(5x + 10) \\ y =   + 3( - 4 + 8x)(5x + 10) \\ y = 3(8 x - 4)(5x + 10) \\  \\ y = 3(8(x -  \frac{1}{2} ))(5(x + 2)) \\ y = 3 \times 8 \times (x -  \frac{1}{2} ) \times 5 \times (x + 2) \\ y = (3 \times 8 \times 5)(x -  \frac{1}{2} )(x + 2) \\ y = 120(x -  \frac{1}{2} )(x + 2)
