Answer:

80π

Step-by-step explanation:

Circle O with radius IO:

large radius = IO = 12 = R

Circle O with diameter JK

IJ = JK = KL = 2 × IO = 24

IJ = JK = KL = 24/3 = 8

small radius = 8/2 = 4 = r

The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.

That is the same as

1 semicircle of radius 12 plus 1 semicircle of radius 4

A = πR²/2 + πr²/2

A = π(12² + 4²)/2

A = 160π/2

A = 80π

Annie says the two expressions are equalized. Is she correct? Explain using different strategies -3x+6 and 3(-x -2).

borishaifa [10]

Step-by-step explanation:

By using Distributive Property on 3(-x - 2),

3(-x - 2) = (3)(-x) + (3)(-2) = -3x - 6.

Since -3x - 6 =/= -3x + 6,

they are not equalized.
