Find two numbers that add to -4 and that multiply to -21.
After playing around with some numbers, I got -7 and 3.
So, the factored form is (x - 7)(x + 3).
Answer:
The answer would be C.
Step-by-step explanation:
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.
