a rectangle has a primeter of 200 ft the length is 4 more feet than the width find the dimensions of the rectangle
zysi [14]

The length and width of the given rectangle are 52 ft and 48 ft respectively.

<h3><u>Solution:</u></h3>

The relationship between the length and breadth is given as following:

The length is 4 more feet than the width

The perimeter of the rectangle is given as 200 ft.

The formula to find the perimeter of a rectangle is:

Perimeter = 2(length + width)

Let length and width of the rectangle be denoted as ‘L’ and ‘B’

The given relationship between length and width can be written in equation form as follows:

L = 4 + B ------ eqn 1

Substitute the value of "L" in perimeter of triangle

200 = 2(4 + B + B)

200 = 2(4 + 2B)

200 = 8 + 4B

4B = 192

B = 48

Since, we know the value of width lets substitute it in eq1 to find the length.

L = 4 + 48

L = 52

Therefore, the length and width of the given rectangle are 52 ft and 48 ft respectively.

Which equation has the solutions X=1 +-SQRT 5?
Vesna [10]

Answer:

D is correct. x^2-2x-4=0

Step-by-step explanation:

We are given the root of the equation

x=1+\pm \sqrt{5}

If we are given solution of the equation then find equation using formula.

If a and b are the solution of equation then equation would be (x-a)(x-b)=0

Here, a=1+\sqrt{5} , b=1-\sqrt{5}

Equation form would be (x-1-\sqrt{5})(x-1+\sqrt{5})=0

Now we simplify the above equation to get correct option.

x^2-x+x\sqrt{5}-x+1-\sqrt{5}-x\sqrt{5}+\sqrt{5}-5=0

x^2-2x-4=0

So, D is correct.  x^2-2x-4=0
