Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. The length is 5 feet le
frutty [35]

Answer:

Width = 17.5 feet,

Length = 82.5 feet.

Step-by-step explanation:

We have been given that Darrin is hanging 200 feet of Christmas garland on the fencing that encloses his rectangular front yard. This means that perimeter of rectangular front yard is 200 feet.

We know that perimeter of rectangle is two times the sum of length and width of rectangle. We can represent this information in an equation as:

2(l+w)=200...(1)

We are also told that the length is 5 feet less than 5 times the width. We can represent this information in an equation as:

l=5w-5...(2)

Upon substituting equation (2) in equation (1), we will get:

2(5w-5+w)=200

2(6w-5)=200

12w-10=200

12w-10+10=200+10

12w=210

\frac{12w}{12}=\frac{210}{12}

w=17.5

Therefore, the width of rectangular front is 17.5 feet.

Upon substituting w=17.5 in equation (2), we will get:

l=5(17.5)-5

l=87.5-5

l=82.5

Therefore, the length of rectangular front is 82.5 feet.

What is the discriminant of the quadratic equation 2x² - x - 3=0?
Tamiku [17]

The given quadratic equation is

2 {x}^{2}  - x - 3 = 0

comparing with

{ax}^{2}  + bx + c = 0

We get ,

a = 2 \\ b =  - 1 \\ c =  - 3

formula :

D =  {b}^{2}  - 4ac \\  \\ D =  {( - 1)}^{2}  - 4 \times 2 \times ( - 3) \\  \\ D = 1 - ( - 24) \\  \\D  = 1 + 24 \\  \\D  = 25.

Discriminant of given quadratic equation is 25 .

option (B) 25 ✔
