6 0

Assuming you want to factor, then you would use the factor by grouping method

x^2+4x + xy+4y

(x^2+4x) + (xy+4y)

x(x+4) + y(x+4)

(x+y)(x+4)

Therefore, x^2+4x + xy+4y factors to (x+y)(x+4)

The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 12 cm, the length of a radius of the circle i
nasty-shy [4]

Answer:

60cm^2

Step-by-step explanation:

We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...

 K = sr

where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.

 K = (12 cm) (5cm) = 60 cm²

_____

A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
