Answer: r=14
Step-by-step explanation:
because they are vertical angles

solving for r you get
r=14
Answer:
the slopes of f(x)and g(x)are the same
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
Answer:
460 m
Step-by-step explanation:
Boundary = perimeter
