Any boy with steps by steps pplease

147²

I assume that u need to find the area so here is the answer

Step-by-step explanation:

first of all calculate the area of the square which is 11cm×15cm=165²

then calculate the small part that is on the upper right

11-9=2 so 9×2=18²

then substract 165-18=147²

b.) divide by -5.

step-by-step explanation:

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
