Hello from MrBillDoesMath!

Answer:

w = 8, -2

Discussion:

The expression is undefined when the denominator is zero. So when does

w^2 - 6w - 16 = 0? Let's factor the expression. A little trial and error shows that 8 + (-2) = 6 (the coefficient of w) and 8 * (-2) = -16 (the constant value) so w^2 - 6w -1 6 = (w-8) (w- (-2)) and the expression equals zero when w = 8 or w = -2

Thank you,

MrB

Answer:

LCM of 21,24 and 26 is 2184

Step-by-step explanation:

We need to find LCM of 21,24 and 26

For finding LCM divide the given numbers by a prime number if two of the numbers are divisible by that prime number

2 | 21,24,26

2 | 21,12,13

2 | 21,6,13

3 | 21,3,13

7 | 7,1,13

13 | 1,1,13

| 1,1,1

So, LCM of 21,24 and 26 is: 2 x 2 x 2 x 3 x 7 x 13 = 2184

How do you find the circumference, radius, and diameter?

Check the picture below.

$\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=2.9 \end{cases}\implies C=2\pi (2.9)\implies C=5.8\pi \implies C\approx 18.22 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{C\div r}{18.22\div 2.9 \approx 6.28}\qquad \stackrel{C\div d}{18.22\div 5.8 \approx 3.14}~\hfill$
