Sally estimates the square root of 50 in the following way: √300 = 3√100 = 3 (10) = 30 (a) Explain why her reasoning is incorrect.
(b) Estimate the square root of 300 to the nearest tenth without using your calculator. Show your work.

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
