You can use logic to say right off the bat that you have 2 one dollar bills
if you said you had 7 instead there would be not enough bills to add up to 82
so that means 4 $5 and 6 $10
check you have 12 bills and it adds up to $82
2 $1
4 $5
6 $10
Y=x^2 + 16 is the correct answer to your question
Answer:
$ 8800
Step-by-step explanation:
The complete question with options is attached in the image below
Amount of profit earned = $ 1320
The profit was 15% of the amount invested.
Let x be the total amount that was invested 30 days ago to buy the shares of the company.
So,
Profit = 15% of the amount invested
1320 = 15% of x
1320 = 0.15(x)
x = 
x = $ 8800
This means, the worth of shares was $ 8800 when they were originally purchased.
For this case we have the following equation:
x ^ 2 + 18x + 32 = 0
Rewriting we have:
x ^ 2 + 18x = -32
By completing squares we have:
x ^ 2 + 18x + (18/2) ^ 2 = -32 + (18/2) ^ 2
Rewriting:
x ^ 2 + 18x + (9) ^ 2 = -32 + (9) ^ 2
x ^ 2 + 18x + 81 = -32 + 81
x ^ 2 + 18x + 81 = 49
(x + 9) ^ 2 = 49
Answer:
(x + 9) ^ 2 = 49
