The length of a rectangular fenced enclosure is 12 feet more than the width

If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.

Answers

Answer 1

Answer:

length = 31 ft

width = 19ft

largest perimeter = 100 ft

Step-by-step explanation:

Let’s say the variable is x, if you draw a rectangle, you’d lable the length as 12+x (because the length is 12 ft longer than the width) and you’d lable the width as x.

Then you’d multply both terms by 2 (and add them up):

2(12+x) + 2(x)

Once you distribute and add...

24 + 2x + 2x

24 + 4x

Then you’d set that equal to 100, since that’s the amount of fencing Dan has:

24 + 4x = 100

Subtract 24 on both sides:

4x = 76

Divide by 4 on both sides:

x = 19

Then you found the width, now to find the length, just add x to 12 (which equals to 31).

Add all the sides up and it equals to 100, which is the largest perimeter than can be created using 100 ft of fencing.

Hope this helped :)

When adding fractions all denominators must be the same. You multiple 2/3 by 4 so it becomes 8/12 and the same with the others. The answer is 19/12

Answer:

Leah's mistake was that she did not change the numerators

the correct value is 19/12

the Step-by-step explanation:

(2/3) + (1/2) + (5/12)

= (2*2/3*2) + (1*3/2*3) + (5/12)

= (4/6) + (3/6) + (5/12)

= (7/6) + (5/12)

= (7*2/6*2) + (5/12)

= (14/12) + (5/12)

= (19/12)

Answer:

1/4096

Step-by-step explanation:

A negative exponent becomes a fraction. 4*3=12. 2^12=4096, so since it's a negative exponent you put it as a fraction. So it's 1/4096.

The simple exponential notation is 4,096.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The exponential notation is;

⇒ [tex](2^{-4} )^-^3[/tex]

Now, Solve the exponential notation as;

⇒ [tex](2^{-4} )^-^3[/tex] = [tex]2^{-4*-3}[/tex]

               = [tex]2^{12}[/tex]

               = [tex]4096[/tex]

Hence, The simple exponential notation is 4,096.

Antoinette solves the linear equation 3 (x minus 3) + 2 x + 9 = 2 x + 2 (x minus 1) using the steps shown below.

Step 1: 3 x minus 3 + 2 x + 9 = 2 x + 2 (x minus 1)
Step 2: 5 x + 6 = 4 x minus 1
Step 3: 5 x minus 4 x = negative 1 minus 6
Step 4: x = negative 7
