Answer:
D
Step-by-step explanation:
Since GH and JK are congruent then the central angles are congruent, that is
∠KOJ = ∠HOG = 68° → D
The answer is A hope you get it right (:
For this case we have the following factorized expression:
Applying distributive property we have:
We add similar terms taking into account that: Equal signs are added and the same sign is placed.

Answer:
22/7 is not pi
Step-by-step explanation:
22/7 is just a close approximation for pi, not pi itself.
If you put 22/7 into a calculator, you get:
3.142857...
While the number pi itself is:
3.1415926...
You can notice that pi is actually different than 22/7, even though the two numbers start out the same and are close to each other. Frequently in geometry, you use 22/7 as pi because it's so close and makes calculation easier.
Hope this helps!
Answer:
-7
-4/21
400
Because 13 times 7 is 91..so -7
-3/7÷9/4 becomes -3/7×4/9. Taking LCM and solving gives -4/21.
last is easy.it becomes (12÷3)×100=400
