If a^2b = 12^2 and b is an odd integer, then a
could be divisible by all of the following
EXCEPT?
A 3 B 4 C 6 D 9 E 12

D

Explanation:

If b is 3 or 9 then a^2 becomes 4*4 or 3*4*4 and a would be either 4 or 4sqrt3

and a would not be divisible by 3,6,9, nor 12

However if the question were about a^2 and b were 3 then the answer would be only 9.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
