The answer is -5. -5 times 4 is -20, plus 9 is -11. -5 times 2 is -10, -1 is -11. -5 works.
$1059.83 Use this formula:

P=principal of 519
r= your rate of 4.2% as a decimal
n=number of compounding periods; yours is daily or 365 day in a year.
t=time involved of the investment in years; yours is 17
378% is the correct answer. Divide 280 by 100 to find 1 percent. Then multiply by 135 to find 135%
Answer:
8. Obtuse
11. Obtuse
Step-by-step explanation:
c^2 = a^2 + b^2
for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute
