Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
If you're talking about the second part of the question where it asks you which facts you included in your answer, you can choose any of them and it will be counted right.
Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
Answer:
12.5
Step-by-step explanation:
Hi there! The anser is 4
First we need to find the value between the stripes. Hence, we need to subtract 15 from 9. Then we get 9 - 15 = - 4. Finally we have to realise that the absolute value stripes make the value insides those stripes positive. So, we get the following:
I 9 - 15 I = I - 4 I = 4
