b^-2-x^-2/b^-1+x^-1
b^-2/b^-1=b^-1
x^-2/x^-1=x^-1
As a result, the simplest form is:
b^-1-x^-1. Hope it help!
Answer:
okay
Step-by-step explanation:
complementary angles are angles that add up to 90 degrees
so what you would do is take each number that you have and subtract it from 90
In the first one you would
1. take 90-80
2. you get your answer of 10!
i hope this helps :)
21= 1,3,7,21
30= 1,2,3,5,6,10,15,30
common factors= 1,3
5/11 because if you simplify starting at 40/88 you get 5/11
