so it's obvious, I guess :)
Now, let's prove is not rational number.
Proof by contradiction.
Let assume is a rational number. Therefore it can be expressed as a fraction where and .
is an even number, so must also be an even number, and therefore also must be an even number. So, we can say that , where .
Since is an even number, then also must be an even number. 3 is odd, so for to be an even number, must be an even number, and therefore is an even number.
But if both a and b are even numbers, then it contradicts our earlier assumption that . Therefore is not a rational number.
Answer:
A, E, F
Step-by-step explanation:

Answer:
q = -6
Step-by-step explanation:
8(q + 6)
= (8×q) (8×6)
= 8q + 48
8q = -48
q = -48/8
q = -6
