2x -x + 9 +3x -2 = 16

COMBINE LIKE TERMS

2x- x + 3x =4x    9 -2=7

4x+7 = 16

4x +7 -7 = 16 -7

4x = 9

4x/4 = 9/4

x = 2.25 or 2 1/4

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.

yarga [219]

Answer:

True , null

Step-by-step explanation:

Mostly the true hypothesis is the null hypothesis .

We test the true hypothesis , the null hypothesis  against the claim provided which is named as alternate hypothesis.

When the false hypothesis is the null hypothesis , type II error is made.

Confounded in statistics means when the alternative explanations cannot be eliminated.But we have the alternate hypothesis in hypothesis testing.

So option 1 is correct
