12 times 2 is 24, and 24 times 2 is 48, so there was 48 cookies
Answer:
It actually gave you the answer.
Step-by-step explanation:
If you read closer, it's telling you the answer. It's giving you examples of radicals and such.
So according to the picture you sent the first part is 2(x-8) (x+6)=0 so it’s the first answer. The second part the answer is (8;0) and (-6;0) the last answer in the second frame.
The reason the answer is those is because it’s using coordinates (x;y) and since we were solving for x we got the x coordinates. But since we got the x coordinates our y coordinates will be 0. If the answer was y=8 than out coordinates would be (0;8). Hope this makes sense

When you add a positive and a negative like you did here it basically is the same as subtracting 5 from 3
