For brainiest:):):):):):)

A: Not proportional

B: Proportional

Step-by-step explanation:

A: 14/4 = 3.5

40/12 = 0.3333333333333

Therefore A is not proportional

B: 3/9 = 0.3333333333333

15/45 = 0.3333333333333

Therefore B is proportional

Hope this helped and pls give brainliest.

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
