Sagot :
The answer is c because you add 4/19x four time because it is a square. That will be 16/19x. Then you add -9 four time for the same reason and end up with -36.
Squares have 4 equal sides, so take 4/19x-9 times 4, and make sure you distribute properly.
[tex]4( \frac{4}{19}x -9)= \frac{16}{19} x-36 [/tex]
[tex]4( \frac{4}{19}x -9)= \frac{16}{19} x-36 [/tex]
