I need help like RN!!!<br> what are the foci of the ellipse? graph the ellipse. 18x^2+36y^=648
Thepotemich [5.8K]
Hi,

18x^2+36y^2=648\\&#10;&#10;\Rightarrow ( \dfrac{x}{6})^2+( \dfrac{y}{3* \sqrt{2} } )^2=1\\&#10;&#10;a=6,\ b=3* \sqrt{2}\\&#10;&#10;c= \sqrt{a^2-b^2} = \sqrt{36-18} =3* \sqrt{2}\\&#10;&#10;
Center is (0,0)
Foci are (-3√2,0) and (3√2,0)

- 7th Grade Work -<br><br> I rlly need help ; - ;
Tanya [424]

Answer:

The length would be 1.5x + 5.

Step-by-step explanation:

So first with this, note that 2 length + 2 height gives the perimeter of the rectangle.

Given this:

2(1/2x + 4) + 2(?) = 4x+18

x+8 + 2(?) = 4x+18

2(?) = 3x+10

? = 1.5x+5

1.5x + 5 = 1.5x + 5

The length would be 1.5x + 5.

To double check, by plugging in 1.5x + 5 back into the equation for the perimeter, you will get the same perimeter:

2(1.5x + 5) + 2(1/2x+4) = P

3x+10 + x+8 = P

4x + 18 = P
