Answer:
-4.4c +1.1
Step-by-step explanation:
The terms that contain c are "like terms". They are -5.8c and +1.4c. The distributive property shows you how to combine these terms.
-5.8c +1.4c = (-5.8 +1.4)c = -4.4c
The terms with no variable are constant terms. They, too, are "like terms" and can simply be added together.
+4.2 -3.1 = 1.1
Then the expression is simplified to ...
-5.8c +4.2 -3.1 +1.4c = (-5.8c +1.4c) +(4.2 -3.1) = -4.4c +1.1
