Step-by-step explanation:
(ax + b)² = a²x² + 2abx + b²
In this case, a = 1, so:
14 = 2b
b = 7
(x + 7)² = x² + 14x + 49
Answer:
61.716 seconds (62 if round up is needed)
Step-by-step explanation:
36 / 7 = 5.143
5.143 * 12 = 61.716
First, we need to know how much profit in dollar value by this method
profit = percentage × whole price
Plug in the numbers to the formula above
profit = percentage × whole price
profit = 40% × 25
profit = 0.40 × 25
profit = 10
The profit Daniel gets is $10
Second, add the original price and the profit together and you'll find the new price.
new price = original price + profit
new price = $25 + $10
new price = $35
Daniel sold the computer game for $35
i would pick number C) since i think it would be the correct answer
