Answer:
168
Step-by-step explanation:
7*-4=-28
-28*-6=168
Answer:
the answer is 'undefined'
Step-by-step explanation:
Cot is defines as (cos x)/(sin x)
So we can rewrite our expression as...
(cos 180°)/(sin 180°) + (cos 180°)/(sin 180°)
or
2(cos 180°)/(sin 180°)
Cos 180° = 1, sin 180° = 0 (you get these from the unit circle)
so we have
2(1/0) = 2/0, which is undefined, because we don't divide by zero
Answer:
true!
Step-by-step explanation:
this is more of a statement then a question.
