Answer:
a =
- b
Step-by-step explanation:
Given
c(a + b) - d = f ( add d to both sides )
c(a + b) = f + d ( divide both sides by the multiplier c )
a + b =
( subtract b from both sides )
a =
- b
Answer:
169
Step-by-step explanation:
if S(n)=n^2
so,S(13)=13^2
n=13
n^2=13^2
=169
Answer:

Step-by-step explanation:

When you add 2pi to the angle, the amount is still the same. Therefore, you can make -17pi/4 positive by adding 6pi to it.
6pi + (-17pi/4)
= 24pi/4 - 17pi/4
= 7pi/4
