Answer:
x=11
Step-by-step explanation:
Using the Exterior Angle Theorem. . .
(3x+8) + (2x+9) = (8x-16)
Solve to get x = 11
Answer: 12.4 cm
Step-by-step explanation:
Since we are given the volums, we can work our way backwards to solve for radius, and then for diameter.





Now that we have r, we multiply it by 2 to get diameter.
2×6.2=12.4
Answer:
15 sides
Step-by-step explanation:
360/24 =15

Answer:
f-¹(x) = -⅕x - ⅘
Step-by-step explanation:
f(x) = -5x - 4 → x = -5y - 4 → 5y = - x - 4 → y = -⅕x - ⅘ → f-¹(x) = -⅕x - ⅘
