Answer:
i dont know 3&4 but #5 is B
Step-by-step explanation:
Lets take this step by step.
1-4-x-(4-1)=-x-2-(4)
first, we'll simplify the parentheses on the left side of the equation.
1-4-x-3=-x-2-(4)
second, we'll combine like terms on the left side.
-6-x=-x-2-(4)
third, we'll combine like terms on the right side of the equation.
-6-x=-6-x
since these are equal, (x=x), we have infinitely many solutions.
Step-by-step explanation:
A
is 45
B
is 45
C
is 90
hence
A+B+C=180
=45+45+90 =180
