1). 18

Step-by-step explanation:

1). The numbers above are real numbers but on a care ful look the number below it is a squrea of the number above but it's position ois swapped.

What am I saying., Let's take for example the number 4.

4² = 16 but what's written is 61

Let's take 5

5² = 25 but what's written is 52

Let's take 6

6² = 36bl but what's written is 63.

So as for 9

9²= 81 but what will be in the box = 18

2).this number two is something special

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

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

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

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
