6

Step-by-step explanation: To evaluate this problem, the first thing

we want to do is plug in the appropriate values for a, b, and c.

When we do that, we get .

A good rule of thumb for problems that involve division bars is to simplify what's above the division bar as much as you can and what's below the division bar as much as you can before you do your dividing.

So up top, we simplify 3(4) to get 12.

Down below, we want to multiply before we subtract.

So 4(3) is 12 and we have 12 - 10 which is 2.

So we have 12 / 2 which simplifies to 6.

a)(x-2)^2+(y-1)^2=9
