Answer:

Step-by-step explanation:

-k - ( -8k + 7)

negative sign is outside the parenthesis. so it should be multiplied with -8k and 7

-k - (-8k + 7) = -k - 8k * (-1) + 7*(-1)

= -1k + 8k - 7

Now -k and 8k are like terms. So, combine them.

= 7k - 7

I NEED HELP PLZ <br> What is length of PR <br> m PZR is 2/3 pie radius

dalvyx [7]

Answer:

Option (4)

Step-by-step explanation:

m(∠PZR) = $\frac{2}{3}\pi$

Radius of the circle = 8

Since, length of an arc = $\frac{\theta}{2\pi }(2\pi r)$

Here, θ = Central angle in radians

From the given formula,

m(arc PR) = $\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)$

= $\frac{2}{6}(16\pi )$

= $\frac{16}{3}\pi$

Therefore, Option (4) will be the correct option.
