Answer: 20d + 5
Step-by-step explanation:
First we need to combine like terms.
In this equation we can see that they're are 3 numbers containing the letter D we have -4, -4, 28.
We're going to combine -4 and -4 to get -8 and then combine -8 to 28 getting 20d
Afterwards we're going to combine 3, 2 equaling 5.
