Solve the equations. Make conclusion.
3|x+12|=6

3

Step-by-step explanation:because you have 12 and add 6 to it and 18/ 6= 3

{-14, -10)

Step-by-step explanation:

Simplify this by dividing both sides by 3.  The result is |x + 12| = 2.  There are actually two correct results.  If it happens that x + 12 is already positive, then x + 12 = 2 and x must be -10.  If it happens that x + 12 is negative, then the equation becomes -(x + 12) = 2, or -x - 12 = 2, or x = -14.

The solutions are {-14, -10).

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
