Is it ever possible that sin (a+b)=⁡ (a+b)= sin⁡ a+sin⁡ b?

if so, explain how. if not, explain why not.

  It will always be the case when A and B are opposites

Step-by-step explanation:

sin(x) = -sin(-x) so ...

  sin(A -A) = (A -A) = sin(A) -sin(A) = 0

That is, the given expression is true when B=-A.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

10 you would take 50/ .2
