Answer:
21,753 is divisible by 3 and 9
Step-by-step explanation:
A number is divisible by 2 if last digit of a number is 0, 2, 4 ,6 ,8
A number is divisible by 3 if sum of digits is divisible by 3.
A number is divisible by 5 if last digit of a number is 0 or 5
A number is divisible by 9 if sum of digits is divisible by 9
A number is divisible by 10 if last digit is 0.
So, according to these rules option (a) 3 ,9 is correct
Therefore , 21,753 is divisible by 3 and 9.
Answer:
14√2
Step-by-step explanation:
A square with a diagonal automatically makes a 45 45 90 triangle (angles) meaning that the two legs are x and the hypotenuse (diagonal) is x√2
If 14 = x then the diagonal is 14√2
You could also solve with the pythagorean theorem
a^2 + b^2 = c^2 so in this case
14^2 + 14^2 = c^2
196 + 196 = c^2
392 = c^2
√392 = √c^2 the 392 is divisable by 196 so you can divide that out as 14
14√2 = c
Since this is a 45-45-90 triangle, n = 6 and m = 6√3.
I hope this helps!
