Question

Combine like terms to create an equivalent expression.

3.4 − 2.8d + 2.8d − 1.3

Answer 1

Answer: the answer is: 5.6d+2.1 thats the final answer to that question.

Step-by-step explanation:

this is how you would combine like terms; you would match whatever #'s or letters together that is how you combine like terms. 

for this one you would do it like this... 2.8d+2.8d-3.4-1.3 (this is how you would combine them) to solve it you would add 2.8d and 2.8d and would minus 3.4 and 1.3.  i didn't solve it yet for you. if you would like me to solve it, let me know. but i explained it to you already on how to solve it. 

hope that helps!
