Answer:
7y4-28y3
Step-by-step explanation:
First you change the formation of the equation, so it looks like -7y3(-y+4). You use distributive property and when distribute the answer will be 7y4-28y3. Hope this helps!

Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
Answer:
The area of the circle is equal to ![25 \pi\ ft^{2}](https://tex.z-dn.net/?f=25%20%5Cpi%5C%20ft%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
where
r is the radius of the circle
In this problem we have
![r=5\ ft](https://tex.z-dn.net/?f=r%3D5%5C%20ft)
substitute
![A=\pi (5^{2})=25 \pi\ ft^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%285%5E%7B2%7D%29%3D25%20%5Cpi%5C%20ft%5E%7B2%7D)
There are multiple answers to this question. To get them, just list the factors of 99 to see how many different pairs of numbers you could use.
99 - 1, 3, 9, 11, 33, 99
Therefore, 1 x 99, 3 x 33, and 9 x 11 are all equal to 99.
Hope this helps!
