Answer:
Step-by-step explanation:
y=3(x-3)(x-4)
=3(x²-4x-3x+12)
or y=3(x²-7x+12)
or y=3x²-21x+36
Answer:
72%.
Step-by-step explanation:
We have been given that a big movie theater had 1,200 seats. 864 of the total number of the seats were sold.
To find what percentage of the total seats were sold we will find 864 is what percent of 1200.

Answer:
B.
Step-by-step explanation:
x represents the amount of guests going to the birthday party, with the amount of money per guest being 12. You would multiply those two together, but as we do not know the total amount of guests, we keep it as a variable. 125 is the amount before the guests even know about the party, so therefore, you would need to use that equation.
Catie used 28 beads on the 7 in. wire because when you divide 68÷17 you get 4 which means that she used 4 beads every 1 in. Then you multiply 4×7 because that's how much we need to figure out and you get 28.
