<u>Answer</u>

C. 4 + 6

D. 3.15151515.. + 4.6

E. √64 × √25

<u>Explanation</u>

A rational number is a number that can be expressed as a quotient or a fraction. That is it can be written as a/b.

π×6 = 6π ⇒ can not be written as a rational number.

√3 + √5 ⇒ the sum of two irrational numbers can not be rational.

4 + 6 = 10. Ten is a rational number. it can be written as 10/1

3.15151515.. + 4.6 = 104/33 + 23/5

= 1279/165

√64 × √25 = 8×5=40 This can be written as 40/1

Which expression is equivalent to the following complex fraction?

sasho [114]

Answer: (D) $\frac{y-x}{y+x}$

Explanation:

$\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}=\frac{y-x}{y+x}$

Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.

2. The area of a square is 72 sq in. What is its side length?

defon

Answer:

$6 \sqrt{2}$

if you don't have to simplify it, it is

$\sqrt{72}$

Step-by-step explanation:

the equation for the area of a square is

$a = {s}^{2}$

substitute 72 for a

$72 = {s}^{2}$

take the square root of both sides to cancel out the square on the s

$\sqrt{72} = \sqrt{ {s}^{2} }$

$\sqrt{72} = s$

if you need it simplified, find the perfect square that makes up 72. It is 36.

$\sqrt{36 \times 2} = s$

take the square root of 36

$6 \sqrt{2} = s$
