Answer:

w = 12

l = 18

Step-by-step explanation:

Hello!

Recall the perimeter of a rectangle is <u>twice the sum of the length and the width of the rectangle.</u>

  • P = 2(l + w)

Let w be the width. The length is 6 less than twice the width. That means, l is 2w - 6.

Plug it into the formula and solve, given that P is 60.

<h3>Solve for w</h3>
  • P = 2(l + w)
  • 60 = 2(2w - 6 + w)
  • 60 = 2(3w - 6)
  • 60 = 6w - 12
  • 72 = 6w
  • w = 12

The width is 12 inches. We can plug in 12 for 2w - 6 to find the length.

<h3>Solve for l</h3>
  • l = 2w - 6
  • l = 2(12) - 6
  • l = 24 - 6
  • l = 18

The length is 18 inches.

The width is 12 inches, and the length is 18 inches.

What is the center of the ellipse x2+5y2–45=0?
jeka94

Answer:

Center is at (0,0)

Step-by-step explanation:

An equation of ellipse in standard form is:

\displaystyle{\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2} = 1

Where center is at point (h,k)

From the equation of \displaystyle{x^2+5y^2-45=0}. First, we add 45 both sides:

\displaystyle{x^2+5y^2-45+45=0+45}\\\\\displaystyle{x^2+5y^2=45}

Convert into the standard form with RHS (Right-Hand Side) equal to 1 by dividing both sides by 45:

\displaystyle{\dfrac{x^2}{45}+\dfrac{5y^2}{45}=\dfrac{45}{45}}\\\\\displaystyle{\dfrac{x^2}{45}+\dfrac{y^2}{9}=1}

Therefore, the center of ellipse is at (0,0) since there are no values of h and k.
