<span>when the altitude is </span>drawn from the vertex of the right angle<span> of a right triangle to its hypotenuse, the altitude equals the product</span> of the two segments of the hypotenuse<span>.
(w+9)</span>²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)

use the same method, z=√(9*11)=3√11

next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55

Maslowich

Answer:

Option C

Step-by-step explanation:

Given : Seth is training for a marathon he’s already running 2.5 miles 5 time a week. It takes him 30 minutes to run 2.5 miles

To find : How long will it take him to run the full 26 miles.

Solution :

Let x be the time taken to cover 26 miles.

It takes him 30 minutes to run 2.5 miles

For 1 minute it cover \frac{2.5}{30} miles.

For x minute it cover 26 miles

For 1 minute it cover \frac{26}{x} miles.

Equating the equation we get,

\frac{2.5}{30}=\frac{26}{x}

\frac{30}{2.5}\times 26=x

x=26\times 12

x=312

Therefore, Option C is correct.
