Yes, an irrational number cannot be counted, for example, pi is an irrational number.
To find the hypotenuse in a 45-45-90 triangle multiply the legs by

So...
The leg is 12 the hypotenuse is 12
Find the Greatest Common Factor (GCF)
<u>GCF = 6y^6</u>
Factor out the GCF. (Write the GCF first. Then, in parenthesis divide each term by the GCF.)
6y^6(24y^8/6y^6 + 6y^6/6y^6)
Simplify each term in parenthesis
<u>6y^6(4y^2 + 1)</u>
Because 0 + 27 is 27 and 10 + 17 is 27 as well
