Answer:
make An equation for both of the numbers in the parentheses .
Step-by-step explanation:
this is how it should look x -2 would be x =15, because you add 2 on both sides , now you have x=15 which should be the answer because 15 is now x and 15 minus 2 = 13
now for the second one
first subtract 10 on both sides then you should get the answer X equals three the reason why it’s like that is because 3 is now x and 3 + 10 = 13.
Hope this helped have a good day :D
Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
Answer:

Step-by-step explanation:
Option A equates to 
Option B equates to 
Option C equates to 
Option D equates to 
which cannot be defined as division by 0 is impossible
Answer:
not really what unit test or topic is that ?
X= 50
Replace the x with the given number.
Y= 50-20
Y= 30
