Astudent factors 3x2 – 12 to the following. 3(x2 – 4) which statement about 3(x2 – 4) is true? a. the expression is equivalent, and it is completely factored. / b. the expression is equivalent, but it is not completely factored./ c. the expression is not equivalent, but it is completely factored./ d. the expression is not equivalent, and it is not completely factored.

Option B is correct that is the expression is equivalent, but it is not completely  factored.

Step-by-step explanation:

We have given an expression

when we take the common factor out which is 3 from the expression we will get

This expression is equivalent but is not completely factored because the term

Hence, Option B is correct.

Option C and D are discarded because given factor is equivalent  

Option A is discarded  because expression is not completely factored.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
