Step-by-step explanation:
done (:P)
First distribute the 2 through the parenthses on the right side.
So we have y - 4 = 2x + 8.
In slope-intercept form, the y is by itself on the left side.
So we add 4 to isolate the y on the left to get y = 2x + 12.
So in slope-intercept form, our equation is y = 2x + 12.
If 1/6 of the pan was left and there were 2 pieces left you just need to set 1/6 equal to 2/some number, this allows you to say that 1/6=2/x --> x/6=2-->x=12.
My explanation might be a little poor since this becomes fairly fundamental later on but hopefully it helps.
Answer:
The area is 105.5ft^2
Step-by-step explanation:

The area of the composite figure
The figure can be divided to 2 shapes
(1) Rectangle: Length = 6ft and Width = 8ft
(2) Trapezoid: Height = 5ft (i.e. 8 - 3), Parallel sides = 9ft and 14ft (i.e. 20 - 6)
The area of the rectangle is:
![Area = 6 * 8 = 48](https://tex.z-dn.net/?f=Area%20%3D%206%20%2A%208%20%3D%2048)
The area of the trapezoid is:
![Area = \frac{1}{2}(9 + 14) * 5](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%289%20%2B%2014%29%20%2A%205)
![Area = \frac{1}{2}(23) * 5](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2823%29%20%2A%205)
![Area = 11.5 * 5](https://tex.z-dn.net/?f=Area%20%3D%2011.5%20%2A%205)
![Area = 57.5](https://tex.z-dn.net/?f=Area%20%3D%2057.5)
So, the area of the garden is:
![Total = 48 + 57.5](https://tex.z-dn.net/?f=Total%20%3D%2048%20%2B%2057.5)
![Total = 105.5](https://tex.z-dn.net/?f=Total%20%3D%20105.5)
Answer:
±sqrt( H *f•c)= L
Step-by-step explanation:
H=L^2/f•c
Multiply each side by fc
H *fc=L^2/f•c * fc
H *f•c=L^2
Take the square root of each side
±sqrt( H *f•c)= sqrt(L^2)
±sqrt( H *f•c)= L
