ANSWER

$12 \sqrt{5}$

EXPLANATION

The given expression is

$\sqrt{2} \times \sqrt{72} \times \sqrt{5}$

The middle radical contains a perfect square.

$\sqrt{2} \times \sqrt{36 \times 2} \times \sqrt{5}$

$\sqrt{2} \times \sqrt{36} \times \sqrt{2} \times \sqrt{5}$

Solve the system of equations 2x + 3y = 40 and –2x + 2y = 20.

Flura [38]

2x + 3y = 40
+
-2x + 2y = 20
___________ Adding both equations

0x + 5y = 60
____________

5y = 60
y = 60/5 = 12

y = 12.

Since we have gotten y =12, and the only option with that is option D.

So we don't have to solve for x.
