The best way to find your answer is to divide 193 by 400 to get .4825 and to make sure if it is the answer you take 400 and multiply .4825 and it will be 193 so .4825 = 48.25%
Answer:
Lisa because quarts are way bigger there pounds and points of milk isnt a thing.
Step-by-step explanation:
(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
