Answer:
12x + 7y
Step-by-step explanation:
First, we need to set up an expression. Since it says "sum" we will be using addition
(4x + 9y) & (8x – 2y)
\/
(4x + 9y) + (8x – 2y)
Next, we can drop the () as there is nothing to distribute
4x + 9y + 8x – 2y
Last, combine the like terms for "simplest terms"
4x + 9y + 8x – 2y
\/
12x + 7y
- There is a 4x and a 8x, this becomes 12x
- There is a 9y and a -2y, this becomes 7y
Hope this helps, have a wonderful day!
