Answer:
A
Explanation:
A is the correct answer. This is an example of using the distributive property by removing the brackets. You can see it if you break it down to two groups.
Group one: 4 * 2
Group Two: 4*5
You could easily combine these, but this exercise was intended to lead you into algebra. The two groups are separated by a plus sign.
4*2 + 4*5
