b) 20c^2 + 2a
c) 12a + 2a
d) 12a - 80

Answer 1

To subtract (7c^2 – 5a) – (522 - 54), remove the parentheses and combine like terms. The final answer is 7c^2 – 5a - 468.

Step-by-step explanation:

To subtract (7c^2 – 5a) – (522 - 54), we need to remove the parentheses and combine like terms.

Within the first set of parentheses, we have 7c^2 – 5a. There are no like terms to combine, so we keep it as is.

Within the second set of parentheses, we have 522 - 54. Subtracting, we get 468.

Now, we can subtract 468 from 7c^2 – 5a to get the final answer.

Therefore, the answer is 7c^2 – 5a - 468.
