Answer:
Option b which is
Step-by-step explanation:
We have been given the discriminant 12
We have to choose the equation which will satisfy the given discriminant.
We will consider all the given equation one by one
First we will take option a which is
Discriminant from the equation we will find by the formula
Here, a=-1,b=8 and c=2 on substituting the values we will get
Hence, option a is incorrect.
Now, we will consider option b which is
Here, a=2,b=6 and c=3 on substituting the values we get
Hence, option b is correct
Therefore, option b is the required answer.
Answer:
$57.5 is the total cost to build the pen.
Step-by-step explanation:
We are given the following in the question:
A livestock pen is built in the shape of a rectangle.
The length of rectangle is two times the width.
Let l be the length of rectangle and w be the width of rectangle. Thus, we can write
Perimeter = 30 feet
Putting values,
The length of rectangle is 10 feet and width of rectangle is 5 feet.
If the material used to build the pen is $ 1.75 per foot for the longer sides and $ 2.25 per foot for the shorter sides
Cost of building =
Thus, $57.5 is the total cost to build the pen.
