Answer:
0.5 + (10c + 8) and 5c - 4
Explanation:
For each set of expressions, we need to eliminate the parenthesis and add the like terms, so for each option, we get:
(9c + 12) - c - 3 and 8c + 9 ----> equivalent
(9c + 12) - c - 3
9c + 12 - c - 3
(9c - c) + (12 - 3)
8c + 9
4c - 2c - 3 and 2 c - 3 -----> equivalent
4c - 2c - 3
(4c - 2c) - 3
2c - 3
5c - 2c + 8 - 4 and 3 c + 4 -----> equivalent
5c - 2c + 8 - 4
(5c - 2c) + (8 - 4)
3c + 4
0.5 + (10c + 8) and 5c - 4 ----> not equivalent
0.5 + 10c + 8
10c + (0.5 + 8)
10c + 8.5
Therefore, the answer is 0.5 + (10c + 8) and 5c - 4.
