Answer:
Step-by-step explanation:
"A" must be added to first expression to get the second one:
- A + 2x² - 3 xy + 5yz = x² - xy + y²
- A = ?
------------------------
- A = x² - xy + y² - (2x² - 3 xy + 5yz) =
- x² - xy + y² - 2x² + 3 xy - 5yz=
- -x² + y² + 2xy - 5yz
Answer:
it's a perfect cube only....
Answer:
1,680 grams
Step-by-step explanation:
To solve this, we can create a proportion using this setup:
grams/people=grams/people
The recipe needs 480 grams for 4 people and x (unknown-what we are trying to find) grams for 14 people.
480 grams/4 people=x grams/14
480/4=x/14
Now, we have to solve for x-the grams needed for 14 people. To do this, we have to get x by itself. x is being divided by 14. To undo this, multiply both sides by 14, because multiplication is the opposite of division.
14(480/4)=(x/14)14
14(480/4)=x
14*120=x
1680=x
