Answer: all coplanar points equidistant from a given point

This is another way of saying "the set of all points that are equally distant from a fixed point" (eg: the set of all points 5 units away from some fixed point). The "fixed point" is the center of the circle. The distance from the center to any point on the circle is the radius.

Marta_Voda [28]

\frac{441}{4}

change the mixed numbers to improper fractions and multiply the numerators / denominators

10 \frac{1}{2} = \frac{21}{2}

\frac{21}{2} × \frac{21}{2} = \frac{441}{4} = 1110 \frac{1}{4}

I think its C, not sure
Alona [7]
Yes; you are correct.
___________________________________________________
The correct answer is:
___________________________________________________
Answer choice:  [C]:  " x³ − 9x² + 23x <span>− 12 " .
___________________________________________________
Note: (a </span>− b) (c − d + e) = ac − ad + ae − bc + bd − be ;
___________________________________________________
          (x − 4) (x² <span>− 5x + 3) = 

   x * x</span>² = x³ <span>− 

   x * 5x = 5x</span>² + 

   x * 3   = 3x <span>−

   4 * x</span>²  = 4x² <span>−

   -4 * 5x =  -20x +

   -4 * 3 =  -12; 
________________________________________
</span>          (x − 4) (x² − 5x + 3) = 

x³ − 5x² + 3x −4x² − (-20x) + (-12) ;

=  x³ − 5x² + 3x −4x² + 20x − 12 ;

= x³ − 5x² − 4x² + 3x + 20x − 12 ;

= x³ − 9x²  + 23x − 12 ;  which is:
