The area of a rectangular wall of a barn is 216 square feet. Its length is 6 feet longer than twice its width. Find the length a
PSYCHO15rus [73]

Answer:

Length is 24 feet and width is 9 feet.

Step-by-step explanation:

It is given that length of a rectangular wall is 6 feet longer than twice its width.

Let x feet be the width of wall.

Length = 2x+6 feet

Area of rectangle is

A=length \times width

A=(2x+6)\times x

A=2x^2+6x

It is given that area of a rectangular wall of a barn is 216 square feet.

2x^2+6x=216

x^2+3x=108

x^2+3x-108=0

Splitting the middle term, we get

x^2+12x-9x-108=0

x(x+12)-9(x+12)=0

(x+12)(x-9)

x=-12,9

Width can not be negative. So width is 9 feet.

Length =2(9)+6=18+6=24\text{ feet}

Therefore, length is 24 feet and width is 9 feet.

Solve the following system of equations.<br> 2x+3y=1<br> 5x-4y=14<br> (See picture attached)
nasty-shy [4]

The solution to the system of equations is x = -1 and y = -1

<h3>How to solve the following system of equations?</h3>

The system of equations is given as:

2x + 3y = 1

5x - 4y = 14

Multiply 2x + 3y = 1 by 2.5

So, we have:

5x + 7.5y = 2.5

Subtract 5x + 7.5y = 2.5 from 5x - 4y = 14

So, we have

7.5y + 4y = 2.5 - 14

Evaluate the difference and the sum

11.5y = -11.5

Divide by 11.5

y = -1

Substitute y = -1 in 2x + 3y = 1

2x + 3(1) = 1

This gives

2x + 3 = 1

Subtract 3

2x = -2

Divide by 2

x = -1

Hence, the solution to the system of equations is x = -1 and y = -1

Q11. 20x=120° (vert opp angles)

x=120÷20

=10

Q12. x+68°=60° (vert opp angles)

x=60-68

=-8

Q13. 80°+x+106°=180° (int angles, u//v)

x+186°=180°

x=180-186

=-6

Q14. 6x+8°=50°

6x=50°-8°

=42°

x=42÷6
