Answer:

OPTION A: 3x - 1 = ± 5

Step-by-step explanation:

We have (3x - 1)² = 25

In OPTION A, Square root is taken on both sides.

This gives us: 3x - 1 = ± 5. And this is the logical follow - up of the previous step.

IN OPTION B: (a - b)² is wrongly expanded. So, this can not be the next step.

In OPTION C: The square root is taken only on the LHS but not on the RHS. So, it is eliminated.

In OPTION D: The square is expanded on LHS whereas on the RHS square root is taken. So, it is not correct and is eliminated.

Therefore, the correct option is A.

So m<1=112 degrees
