Solve the given system of equations by either Gaussian elimination or Gauss-Jordan elimination. (If the system is inconsistent, enter INCONSISTENT. If the system is dependent, express x, y, and z in terms of the parameter t.) 5x − 2y + 4z = 12 x + y + z = 8 4x − 3y + 3z = 4 (x, y, z) = 2(−3z+14) 7, −z+28 7,t

Required unique solutions are 8, 4, 0 and the system is consistant.

Step-by-step explanation:

Given system of equation,

5x-2y+4z=12

x+y+z=8

4x-3y+3z=4

To find solution of the system re-write as,

Hence solutions are 8, 4 and 0. And it is a unique solution. Therefore system is consistent.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
