Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
Answer:
x = (18 + 3y)/2 y = (18 - 2x)/3
Step-by-step explanation:
For whichever variable you want to solve for, isolate it on one side. For example, if you want to solve for x, first add 3y to each side.
2x = 18 + 3y
Then, divide everything by two.
x = (18 + 3y)/2

Answer:
The original award is of $66666.67 and David receives the most money.
Step-by-step explanation:
Let us assume that the total prize money is $x.
Now, Ailin receives $10000 plus 
of what then remains, and David receives $16000 plus 
of what then remains, and finally Rashaad receives $18000.
So,from the conditions given above we can write
![[10000 + \frac{x - 10000}{5}] + [16000 + (x - 10000 - \frac{x - 10000}{5}) \times \frac{1}{4}] + 18000 = x](https://tex.z-dn.net/?f=%5B10000%20%2B%20%5Cfrac%7Bx%20-%2010000%7D%7B5%7D%5D%20%2B%20%5B16000%20%2B%20%28x%20-%2010000%20-%20%5Cfrac%7Bx%20-%2010000%7D%7B5%7D%29%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%5D%20%2B%2018000%20%3D%20x)
⇒ 
⇒ 
⇒ 
⇒ 
⇒ x = $66666.67
Therefore, Ailin receives ![[10000 + \frac{66666.67 - 10000}{5}]](https://tex.z-dn.net/?f=%5B10000%20%2B%20%5Cfrac%7B66666.67%20-%2010000%7D%7B5%7D%5D)
= $21333.34
And David receives ![[16000 + (66666.67 - 10000 - \frac{66666.67 - 10000}{5}) \times \frac{1}{4}]](https://tex.z-dn.net/?f=%5B16000%20%2B%20%2866666.67%20-%2010000%20-%20%5Cfrac%7B66666.67%20-%2010000%7D%7B5%7D%29%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%5D)
= $27333.33
The original award is of $66666.67 and David receives the most money. (Answer)
