ANSWER

b=11

EXPLANATION

The given quadratic equation is

(2x - 1)(x + 6) = 0

We expand to get:

2 {x}^{2}  + 12x - x - 6 = 0

We simplify further by combining the x terms.

2 {x}^{2}  + 11x - 6 = 0

This is the standard form.

Comparing to

a{x}^{2}  + bx  + c= 0

We have b=11

You have 1200 feet of fencing and you want to make two fenced in enclosures by splitting one enclosure in
NARA [144]

Let x = length and y = width

You would have 2 lengths, so 2x and 3 widths, so 3y

Those need to equal total length of fence:

2x + 3y = 1200

The 3 widths would equal total fence minus the 2 lengths:

3Y = 1200-2x

Solve for y: y = 400 -2/3x

Area = length x width = xy. Replace y :

Area = x(400-2/3x) = 400x-2/3x^2

Differentiate:

400-4x/3 =0

4x/3 = 400

4x = 1200

X = 300

Y = 400-2/3(300) = 200

The dimension would be 300 ft x 200 ft

What is the value of x?<br><br> Please help! Thanks!
leonid [27]

Answer:

x=75

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

42           50

------ = ----------

42+63        50+x

42           50

------ = ----------

105          50+x

Using cross products

42(50+x) = 50*(105)

2100+42x = 5250

Subtract 2100 from each side

2100-2100+42x = 5250-2100

42x =3150

Divide by 42

42x/42 = 3150/42

x = 75
