C probably because a numerical expression uses numbers and does not have any equal signs at the end and it seems like the best answer
is an irrational number i.e. it cannot be written in the form of
where p and q are integers and q is never equal to 0.
By multiples of
, we can write like:
1
=
= 3.14
2
= 2*3.14 = 6.28
3
= 3*3.14 = 9.42
In the same way, any integer n when multiplied by
, is a multiple of
15² + 36² = 39² correct
24² + 45² = 51² correct
21² + 72² = 76² wrong
18² + 24² = 30² correct
The third one is wrong because 21² + 72² = 75²
Hope This Helps! :)
The image of the number line is missing, so i have attached it.
Answer:
5 metres
Step-by-step explanation:
From the attached image, we can see that point A is at -2.5 while point B is at 2.5.
Thus,distance between points A and B is; 2.5 - (-2.5). Where -2.5 is the additive inverse of 2.5.
Minus outside bracket when multiplied by minus inside the bracket will yield a positive sign.. Thus: distance = 2.5 + 2.5 = 5 m
