Don’t Fall for This SAT Math Trap! ! SAT Math Hack #6

Описание: This SAT Math question looks intimidating, but there’s an easy shortcut most students miss!

Instead of messy algebra, just plug in the answer choices and test. You’ll see that only x = 9 works perfectly.

Remember, when you see radicals (square roots) on the SAT, you can test the choices instead of isolating x.

Tip: Plug–don’t–panic!
