Guys please help me with this

The equation of the elipse is

Step-by-step explanation:

Equation of an elipse:

The equation of a elipse with centre has the following format:

Centre at (0,0):

Means that .

So

Vertex at (13,0):

Vertex at 13 means that

Focus at (-12,0):

Means that

We have that:

So

So, the equation of the elipse is

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
