Answer:
<h3>
5.0</h3>
Step-by-step explanation:

quadratic formula:
x = <u>-b ± √(b² - 4ac)</u>
2a
7x² - x = 7
subtract 7 from both sides:
7x² - x - 7 = 0
plug values into the quadratic formula:
x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>
2(7)
simplify:
x = <u>1 ± √(197)</u>
14

Answer:
<u>$50,000</u>
Step-by-step explanation:
Formula to find interest :
I = Prt
Solving :
- I = (20,000)(0.06)(25)
- I = (1.5)(20,000)
- I = (30,000)
Future value :
- P + I
- 20,000 + 30,000
- <u>$50,000</u>
