Which expressions are equivalent to 12r-5?

The first answer(A) ans the second one(B)

Step-by-step explanation:

A. I did the operations in the parenthesis first and then did the distributive property.  I then simplified.

6(2r+(-1))+1

6(2x-1)+1

12x-6+1

12x-5

-4(2+(-3r))+3

-4(2-3r)+3

-8+12r+3

12r-5

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

the anwser is d) 75°
