Aka, wat is n=3
substute 3 for n
T(3)=6(3)+2
t(3)=18+2
t(3)=20
answer is 20
The second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
<h3>
Which statement is always true?</h3>
Remember that for integer numbers, we have the following properties:
- Commutative property: A + B = B + A
- Associative property: (A + B) + C = A + (B + C)
Now, in this case we know that a and b are integer numbers, first we can see that the second statement is:
B: a + b = b + a
Which is the commutative property, so we know that this statement is true.
The other 3 statements are false. You can see it by evaluating a = 0 and b = 1.
