Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
if (x + 2) is a factor of x^3 − 6x^2 + kx + 10, k = [ ] .

k = -11.

Step-by-step explanation:

By the Factor theorem if x + 2 is a factor of this expression then f(-2) = 0, so we have:

(-2)^3 - 6(-2)^2  - 2k + 10 = 0

-8 - 24 + 10 = 2k

k = -22/2

k = -11.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
