The first 3 terms of
n+5
3n -1

3n^2+7n-5

Step-by-step explanation:

Distribute n to 3n and -1

Distribute 5 to 3n and -1

3n^2+7n-5

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

step-by-step explanation:

20 ≤ x + 15 ≤ 55

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
