Apply the Distributive Property to rewrite 2(6 - x) = 3. Then solve th equation Apply the Distributive Property to rewrite 2(6 - x)= 3. Choose the correct answer below, A. 6(2) – 6X = 3 OB. 2(6) - 2x = 3 OC. 6(2) +GX = 3 ED. 2(6) + 2x = 3​

Answers

Answer:

x = ⁹⁄₂ Or 4.5

Explanation:

2(6 - x) = 3

Apply Distributive Property

2(6 - x) = 3

2(6) = 12, 2(x) = 2x12 - 2x = 3

12 - 2x = 3

Subtract 12 From Both Sides

12 - 2x - 12 = 3 - 12

Simplify

-2x = -9

Divide Both Sides By -2

-2x / -2 = -9 / -2

Find the missing length

Answers

Answer: 15

Step-by-step explanation:

For this you will have to use pythagoras’ theorem.

The formula for the shorter side of this triangle is u²=c²-b² (or in this case u²=17²-8²).

17²=289

8²=64

The formula becomes u²=289-64 or u²=225

Then to find u on its own you have to square root 225.

The square root of 225 is 15.

Cynthia Besch wants to buy a rug for a room that is 24 ft wide and 32 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 560 square feet of carpeting. What dimensions should the rug​ have?

Answers

Answer:

[tex]D=(20.42)(28.42)[/tex]

Step-by-step explanation:

From the question we are told that

Width [tex]W=24ft[/tex]

Length [tex]L=32ft[/tex]

She can afford to buy 560 square feet of carpeting

Let

[tex]S=width\ of\ strip[/tex]

Generally the Dimension of the rug is mathematically given as

Width of Rug [tex]W' = (24- 2S)ft[/tex]

Length of Rug [tex]L'= (32-2S) ft[/tex]

Generally the width of strip S is mathematically given by

[tex](32-2s)*(24-2s)=560[/tex]

[tex]-4s-112s+208=0[/tex]

[tex]s_1=-29.7\\s_2=1.748[/tex]

Therefore the width is

[tex]s=1.748[/tex]

Generally the dimension of the rug D is mathematically given as

Width of Rug [tex]W' = (24- 2s)ft[/tex]

[tex]W' = (24- 2(1.79))ft[/tex]

[tex]W' =20.42ft[/tex]

Length of Rug [tex]L'= (32-2S) ft[/tex]

[tex]L'= (32-2(1.79)) ft[/tex]

[tex]L'=28.42 ft[/tex]

Therefore dimension of Rug is given by

[tex]D=(20.42)(28.42)[/tex]
