Question

Need an explanation with the answer

Answer 1

Answer:

(C) & (D)

Step-by-step explanation:

• 3$x$ + 9$x$ + 5$x$ = 27$x^{2}$ + 5$x$

  =>  17$x$   =   27$x^{2}$ + 5$x$

  =>  17$x$   ≠   32$x^{2}$

• 18$z^{3}$  =  2z + 3z × 3z

   =>  18$z^{3}$ = 2$z$ +  9$z^{2}$

   =>  18$z^{3}$ ≠ 11$z^{2}$

• 14$y^{2}$ = 2$y$(4$y$) + 6$y^{2}$

    =>  14$y^{2}$ = 8$y$ + 6$y^{2}$

    =>  14$y^{2}$ = 14$y^{2}$

• 5$w$(2$w$ + 3) + 2$w$ = 10$w^{2}$ + 17$w^{2}$

    =>  10$w^{2}$ + 15$w$ + 2$w$ = 27$w^{2}$

    =>  10$w^{2}$ + 17$w$  = 27$w^{2}$

    =>  27$w^{2}$  =  27$w^{2}$

Pss...I'm not sure whether it's right or wrong...If it's wrong pls report the answer ASAP...
