Answer:
12
Step-by-step explanation:
We know that 1/3 of a pizza is cheese meaning that 6 pizzas are made of cheese and there are only two leaving the rest pepperoni and 12 are left if we subtract the cheese pizzas minus the 18 pizzas we have 12 which are pepperoni.
Answer:
Step-by-step explanation:
<u>Even function has following property:</u>
<u>It is easy to show this works with the second choice only. All the others don't work:</u>
- g(x) = (x - 1)² + 1
- g(-x) = (-x - 1)² + 1
This is not correct as x - 1 ≠ -x - 1 so as their squares, so g(x) ≠ g(-x)
The last two choices are not even similarly.
Answer:
3/40
Step-by-step explanation:
used a calculator
(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
