Answer:

Step-by-step explanation:

Since it's an isosceles triangle, WX=WZ= 2n-5

Perimeter = n + (2n-5) + (2n-5)

= 5n - 10

The Perimeter is given to be 20

5n - 10 = 20

5n = 30

n = 6

Answer:

$\frac{1}{16}$ or in decimals: 0.0625

Step-by-step explanation:

4*4*4 is 4³ or 16*4 or 64

4*4*4*4*4 is $4^{5}$ or 16*16*4 or 256*4 or 1024

We have $\frac{64}{1024}$ which divided by 8 is $\frac{8}{128}$ which divided by 8 again is $\frac{1}{16}$
