Answer:

Missing constant: 100

Step-by-step explanation:

perfect square  (a - b)^2 = a^2 - 2ab + b^2

In this case

20x = 2 * x * 10

and

10^2 = 100

so

(x - 10)^2 = x^2 - 20x + 100

a stock was selling at $120 per share. a month later, it was selling at $150 per share. what is the percent increase?
goldfiish [28.3K]

Answer:

25%

Step-by-step explanation:

The formula to find percent increase is 100 * \frac{final-initial}{|initial|}. We're given the initial value as 120 and the final value as 150.

  • 100*\frac{150-120}{|120|}
  • 100*\frac{30}{120}
  • 100*\frac{1}{4}
  • 100/4
  • 25

Therefore, the percent increase is 25%.
