The gcf of any two even numbers is always even. determine whether the statement is true or false. if true, explain why. if false, give a reason.

To solve this problem, we must use the pythagorean theorem. 12 is the hypotenuse or c and 5 is b.

a^2 + (5)^2 = (12)^2. Square the appropriate numbers.

a^2 + 25 = 144. Subtract 25 from each side.

a^2 = 119. Take the square root of each side.

a = √(119). This is only half the value of x. Multiply √(119) by 2

Your answer should be 21.8
