√5 + √36 = √5 + 6   <--- irrational 
√9 + √24 = 3 + √24   <--- irrational
2 * √4 = 2 * 2 = 4   <--- rational 
√49 * √81 = 7 * 9 = 63   <---rational
3√12 = 3√(4 * 3) = (3 * 2)√3 = 6√3    <---irrational

(B) The given expression is:

\sqrt{5}+\sqrt{36}

which can be written as:

\sqrt{5}+6 which is an irrational number.

(C) The given expression is:

\sqrt{9}+\sqrt{24}

which can be written as:

3+\sqrt{24} which is an irrational number.

(D) The given expression is:

2{\times}\sqrt{4}

which can be written as:

2{\times}2=4 which is a rational number.

(E) The given expression is:

\sqrt{49}{\times}\sqrt{81}

which can be written as:

7{\times}9=63 which is a rational number.

(F) The given expression is:

Say that a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse. Find b if a = 21 and c =
maria [59]
When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be

c^2 = a^2 + b^2

If a = 21 and c=29, thus

b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units. 

Thus, the answer is <span>D) B = 400</span>
