What property are

3c+5 (2+c) = 3c+5 (2) + 5c

=3c+5c+5 (2)

= (3c+5c) + 5 (2)

= (3+5) c+5 (2)

=8c+10

We applied distributive, associative and commutative properties to solve the calculus.

Step-by-step explanation:

3c+5 (2+c) = 3c+5 (2) + 5c (distributive property)

=3c+5c+5 (2) (commutative property)

= (3c+5c) + 5 (2) (associative property)

= (3+5) c+5 (2) (distributive property) by the shape of common factor extraction).

=8c+10 3+5 is a simple add and 5.2 is a simple multiplication)
