Answer:
<h2>B) 0</h2>
Step-by-step explanation:
The slope of a horizontal line is equal to 0.
The slope of a vertical line is undefined.
The formula of a slope:
![m=\dfrac{y_2-y_!}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_%21%7D%7Bx_2-x_1%7D)
Put the coordinates of the pojnts from the graph (2, 9) and (4, 9):
![d=\dfrac{9-9}{4-2}=\dfrac{0}{2}=0](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7B9-9%7D%7B4-2%7D%3D%5Cdfrac%7B0%7D%7B2%7D%3D0)

Answer:
I think the answer is C
Step-by-step explanation:
21 a² - 57 a + 30 =
= 3 ( 7 a² - 19 a + 10 ) =
= 3 · 7 · ( a - 5/7 ) · ( a - 2 ) =
= 3 ( 7 a - 5 ) ( a - 2 )
So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation
![x^{2}=320](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%3D320)
which simplifies to
There are 4 quarts in a gallon. 4 times 5 is 20 and 28 divided by 20 is 1.4. So the cost of one quart of the oil is $1.40
