Answer: C
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
(f+g)(x) means add f(x) and g(x) together:
(x/2)-2 + 2x^2 +x -3
collect all the like terms:
2x^2
(x/2) + x = 3/2x (explanation below)
-2 -3 = -5
x/2 + x can be turned to 1x/2 + 2/2x (2/2 = 1, so when you simplify it to 1x, it is still x)
The answer is c because if you have a square and you look at a reflection you can see that a square has 4 sides so if you look at the reflection you would see another of the square. So what you would do is 4+4 which equals to 8.
