2 x (5-2)^3
2 x (3)^3
2 x 27

A. Given (This is part of the original problem)
b. Supplementary angles form 180 degrees (The definition of supplementary angles is that two or more angles have a sum of 180 degrees. DC is a straight line and has a measure of 180 degrees)
c. Substitution (Given the two previous statements, they are each equal to 180 degrees. Since 180=180 then you can substitute the angles in the equation.)
d. Subtraction (m<2 is being subtracted)
e. Subtraction postulate (Since the same quantity was being subtracted from each side of the equation, they are still equal)
Answer:
f(g(x))= x-2
Step-by-step explanation:
f(g(x))= (x-4)+2 -plug g(x) into the place of x in the f(x) function
f(g(x))= x-4+2 -parentheses aren't needed
f(g(x))=x-2 -combine like terms
