Answer:
Step-by-step explanation:
ax² + bx + c = a(x - 
)(x - 
)
D = b² - 4ac
= ( - b ± √D ) / 2a
~~~~~~~~~~~~
Let x² = y , then y² + 8y - 9
Find the roots of equation y² + 8y - 9 = 0
D = 64 + 36 = 100 = 10²
= ( - 8 - 10) / 2 = - 9
= ( - 8 + 10) / 2 = 1
y² + 8y - 9 = (y - 1)(y + 9) = (x² - 1)(x² + 9)
x² = 1 ⇒ = ± √1
+ 8x² - 9 = (x - 1)(x + 1)(x² + 9)
Answer:
27,000,00
Step-by-step explanation:
The Interest rate is 5% and the borrowed money is $20m. You have to multiply $20m by 5%, which gives you 1m. Then for each year, you must add the $1m to the overall money($20m), meaning you have to add $1m dollars to $20m for 7 years. After the 7 years, there are $7m for interest, and in addition to that, you must add it to $20m. Therefore, overall, Antony would have to pay $27m after 7 years.
