Answer:
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.
Answer:
x= -1
Step-by-step explanation:
-4(2x+5)+x+2= -11
-8x-20+x+2
-7x-18= -11
+18 +18
-7x= 7
-7x/-7 =7/-7
x= -1
Hope this helps!
