6 0

Answer:

Step-by-step explanation:

3kx + 24 = 9kx

First subtract 3kx to both sides.

24 = 9kx  - 3kx

24 = 6kx

Divide both sides by 6

24/6 = kx

4 = kx

Divide both sides by k.

4/k = x

galben [10]

Answer:

the answer is B

Step-by-step explanation:

area of the minor arc is teter all over 360 times 2 pie r square.

that is

\frac{?}{360}  \times 2\pi {r}^{2}

= but because the question said for length AB, youvhave to use only one radius.

\frac{160}{360}  \times 2 \times  \pi \times 9

You the use 40 to cancel 160 and 360 to get 4 all over 9 times 2 pie times 9.

\frac{4}{9}  \times 2 \times \pi \times 9

You then cancel 9 with 9 to get 4 times 2 times pie

4 \times 2 \times \pi

this is equal to

8\pi
