Do you guys know the answer for number 3

{3,23,39}

Step-by-step explanation:

I think that thing inside the box says 4x-5.

The numbers we are putting in are 2,7, and 11.

So when we put 2 in we get 4(2)-5 which is 8-5=3.

When we put 7 in we get 4(7)-5 which is 28-5=23.

When we put 11 in we get 4(11)-5 which is 44-5=39

So the answer is {3,23,39}.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
