Step-by-step explanation:
A is correct option there are no real roots
because discriminant is less than zero
Answer:
J=63
Step-by-step explanation:
3b+27=2b+57
subtract 27 from both sides
3b=2b+30
subtract 2b from both sides
b=30
K+J=180
substitute the value of b into K
2(30)+57+J=180
117+J=180
subtract 117 from both sides
J=63
Answer:
A =28 pi cm^2
Step-by-step explanation:
First find the area of the larger circle
A = pi r^2
A = pi (8)^2
A = 64 pi
Find the area of the smaller circle
A = pi r^2
A = pi 6^2
A = 36 pi
The shaded area is the larger circle minus the smaller circle
A shaded = 64 pi - 36 pi
A =28 pi cm^2
