Question

(x-a)×(×-b)-(×-c) --------- (×-z) =
​

Answer 1

Answer:

answer is 0 because there will be a situation when (x-x)=0 and when we multiply by 0 to any number it will be 0

Answer 2

${❥}\fbox\red{A}\fbox\orange{N}\fbox\purple{S}\fbox\green{W}\fbox\blue{E}\fbox\pink{R}$

Required answer-:

For the reaction : xA+yB→zC−x1dtd[A]=−y1dtd[B]=z1dtd[C].........(1)Given that,−dtd[A]=−dtd[B]=1.5dtd[C].........(2)Multiplying equation 2 by 31, we get−31dtd[A]=−31dtd[B]=21dtd[C].........(3)On comparing equation 1 and 3, we get value of x=3,  y=3, z=2Hence, option C is correct.
