Answer:
14 correct and 11 wrong
Step-by-step explanation:
If you got a 56% , we need to change this to decimal form 56% = .56
This is the percent you got right
.56* 25 = 14
You got 14 questions right
To determine the number of questions you got wrong, take the total number of questions minus the number you got right.
25-14 =11
You got 11 wrong
(3c^2 − 5cd + d^2) − (7c^2 + 4cd − 9d^2) =
1. Drop the parentheses around the first polynomial since they are not needed.
= 3c^2 − 5cd + d^2 − (7c^2 + 4cd − 9d^2)
2. To drop the parentheses around the second polynomial, every sign inside changes.
= 3c^2 − 5cd + d^2 − 7c^2 - 4cd + 9d^2
3. Combine like terms. Like terms have the same variables and exponents.
= 3c^2 - 7c^2 - 5cd - 4cd + d^2 + 9d^2
= -4c^2 - 9cd + 10d^2
