Answer:
This is probably wrong. But i hope this helps anyways
Step-by-step explanation:
If the perimeter is twice its width, and the perimeter is 60. That means the whole length of the shape youre looking at is 120. (60•2) we can assume that this shape has 4 sides. 60/4. Thats 15. So the sides are 4 ft. The length is at the top and bottom is 15. 15•4 = 60. There ya go
Ok so parallel equations mean they have equal slope, but different y intercepts. Here, we can solve and get the equation:
y=2/5x-7/5

Answer: 13 is c im pretty sure and 14 is a im think hope fully it helps
Step-by-step explanation:
For this case we have the following quadratic equation:
![-3x ^ 2 + x-4 = 0](https://tex.z-dn.net/?f=-3x%20%5E%202%20%2B%20x-4%20%3D%200)
Where:
![a = -3\\b = 1\\c = -4](https://tex.z-dn.net/?f=a%20%3D%20-3%5C%5Cb%20%3D%201%5C%5Cc%20%3D%20-4)
By definition, the discriminant of a quadratic equation is given by:
![d = b ^ 2-4 (a) (c)](https://tex.z-dn.net/?f=d%20%3D%20b%20%5E%202-4%20%28a%29%20%28c%29)
We have to:
Two different real roots
Two different complex roots
Two equal real roots
Substituting the values we have:
![d = 1 ^ 2-4 (-3) (- 4)\\d = 1-48\\d = -47](https://tex.z-dn.net/?f=d%20%3D%201%20%5E%202-4%20%28-3%29%20%28-%204%29%5C%5Cd%20%3D%201-48%5C%5Cd%20%3D%20-47)
So, we have two different complex roots
Answer:
Two different complex roots
