PLEASE HELP ASAP!!!! Thanks!!

Answer:

1.2 cm

Step-by-step explanation:

Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).

The area of circumscribed quadrilateral is

A=p\cdot r,

where p=\dfrac{a+b+c+d}{2} is semi-perimeter and r is radius of inscribed circle.

In your case, A=12\ cm^2

If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so

a+c=b+d=10\ cm,

so

P=10+10=20\ cm\\ \\p=\dfrac{20}{2}=10\ cm

Now

12=10\cdot r\Rightarrow r=\dfrac{12}{10}=1.2\ cm

Please help I don’t understand.I need to know if it is a linear function and how to write it in standard form. :)
Ipatiy [6.2K]
A linear function is one whose formula can be written in the form

Ax + By = C  where A, B, C are real numbers and A, B are not both 0.  (This is standard form, too.)

\frac{x+4}{2} = \frac{y-4}{3}

"Cross multiply."

3(x+4) = 2(y-4) \\ 3x+12 = 2y-8

Subtract 12.

3x=2y-20

Subtract 2y.

3x-2y=-20

This matches up with standard form with A = 3, B = -2, C = -20.

It's a linear function.
