Answer: <u>C. 20-.40p</u>
Step-by-step explanation:
We know that from the given information that each pound is worth 40 cents, and that its being subtracted from the twenty dollar bill.
"Why are the others choices wrong?"
A. p-20, isn't the proper equation due to the stated information.
B. B. 20 -40p, this equation has Zelma pay $40 dollars each pound, which isn't correct due to what the text has stated ("for 40 cents per pound").
D. 40p-20, from the given text, this equation is wrong ("She pays the clerk with a twenty-dollar bill), it never states that she will be charged twenty dollars, or be given forty for each pound.

Answer:
-5/4, 5
Step-by-step explanation:
h(x)=(-4x -5)(-x +5) = 0
-4x-5 = 0
x = -5/4
-x+5 = 0
x = 5
Answer:
Step-by-step explanation:
it depends on if you are adding A and B it would be P= 0.7 and if you are multiplying it would be P= 0.12
Answer:
Scalene triangle
Step-by-step explanation:
Coordinates of the vertices of the triangle are,
W(-7, 1), X(0, -4) and Y(2, 3)
We will use the formula to get the distance between two points.
d = ![\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28y_2-y_1%29%5E2%2B%28x_2-x_1%29%5E2%7D)
WX = ![\sqrt{(-4-1)^2+(0+7)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-1%29%5E2%2B%280%2B7%29%5E2%7D)
= ![\sqrt{74}](https://tex.z-dn.net/?f=%5Csqrt%7B74%7D)
WY = ![\sqrt{(1-3)^2+(-7-2)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%281-3%29%5E2%2B%28-7-2%29%5E2%7D)
= ![\sqrt{85}](https://tex.z-dn.net/?f=%5Csqrt%7B85%7D)
XY = ![\sqrt{(3+4)^2+(2-0)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%283%2B4%29%5E2%2B%282-0%29%5E2%7D)
= ![\sqrt{49+4}](https://tex.z-dn.net/?f=%5Csqrt%7B49%2B4%7D)
= ![\sqrt{53}](https://tex.z-dn.net/?f=%5Csqrt%7B53%7D)
Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
