The answer is y is equal to 5.

The symbol in the corner tells us that the corner is 90 degrees. So much sides added together is 90.
9y - 6 + 51 = 90
9y + 45 = 90
9y = 45
y = 5

Explain why multiplying two irrational numbers could result in either an irrational number or a rational number.

Nimfa-mama [501]

Because if you multiply 2 different irrational numbers (like the following)
$\sqrt{3} \times \sqrt{17}$
You will get an irrational answer.

BUT
if you multiply the same square root (which are both irrational, you get a rational number)

$\sqrt{3} \times \sqrt{3} = 3$
