Assuming that is the circumradius:
Polygon Area = [r^2 * n * sin (360 / n)] / 2
Polygon Area = (25 * 20 * sin (18)) / 2
Polygon Area = (500 * 0.30902) / 2
Polygon Area = <span> <span> <span> 77.255 </span> </span> </span>

X+5/x^2+x-12 <br> What are the restrictions for x
soldier1979 [14.2K]

x ≠ - 4, 3

the denominator of the fraction cannot equal zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the values that x cannot be

solve x² + x - 12 = 0

(x + 4)(x - 3) = 0

equate each factor to zero abd solve for x

x + 4 = 0 ⇒ x = - 4

x - 3 = 0 ⇒ x = 3

restrictions on x are : x ≠ - 4, 3
