Answer:

$c=3\sqrt{13}$

Step-by-step explanation:

Pythagorean Theorem: In the right triangle the square of longer side is equal to the sum of the squares of other sides.

$c^2=a^2+b^2\\\\c^2=6^2+9^2\\\\c^2=36+81\\\\c^2=117\\\\c^2=3\times 3\times 13\\\\c=\sqrt{3\times 3\times 13}\\\\c=3\sqrt{13}$

Simplify the following:
-3 w - 5 (6 z - 2 W) - 5 z
-5 (6 z - 2 W) = 10 W - 30 z:
-3 w + 10 W - 30 z - 5 z
-30 z - 5 z = -35 z:
Answer: -3 w + 10 W + -35 z
