Wait so are the sides of the octagon 9 inches each or do we have to find that?
Answer:
9 and 4/5
Step-by-step explanation:
-2(3+3) = -12
f(x) is telling you to substitute all the x values into the equation. The f(x) of the function is 3, telling you to plug in 3 in the equation. This leads to -2(6) = -12.
