Answer: -20, 6, 2, 5

Step-by-step explanation:

a = 5, b = -4, c = 10

12. ab = 5(-4) = -20

13. b + c = -4 + 10 = 6

14. c/5 = 10/5 = 2

15. c - 5 = 10 - 5 = 5

9.42 Units

Step-by-step explanation:

Since the angle shown is 90 degrees we can deduce that the rest of the arc is 270 degrees therefore we can make the fraction:

270/360; 360 being the total angle measurement of a circle

270/360 simplifies to 3/4

The fraction represents how much of the circle that arc covers

Now we have to find the circumference which would be

2(3.14)r

r = 2 therefore: 2(3.14)2 = 12.56

Now that we have the circumference of the WHOLE circle we multiply it by 3/4 to find out the arc length

Which gives us  9.42
