1: The square root of 8 is irrational because it is not a perfect square

2: The square root of 49 is rational because it is a perfect square (7x7)

3: False, decimals that terminate are rational numbers.

Answer:

put 0 in y<=2x+4

y<=4

so if y=4, then y<=2x+4 is true, but y can not equal 4 because they don't want y<2x+4 be true. So y should be 3, 2, 1, 0.

(0, 2)

put -2 in y<=2x+4

y<=0

so if y=0, then y<=2x+4 is true, but y can not equal 0 because they don't want y<2x+4 be true. So y should be negative.

(-2, -1)

Answer: $\textsf{Option A, 13}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Side length = 9 units}$

Find: $\textsf{Diagonal length}$

Solution: The diagonal length can be easily determined using an equation which uses the side length of a square multiplied by the square root of 2. All we need to do is plug in the values and simplify the expression.

<u>Plug in the values</u>

$\textsf{Diagonal = Side length} * \sqrt{2}$

$\textsf{Diagonal = 9 units} * \sqrt{2}$

<u>Simplify the expression</u>

$\textsf{Diagonal = 9 units * 1.4142}$

$\textsf{Diagonal = 12.73 units}$

Looking at the answer options that have been provided, the option that best fits our scenario is option A, 13.
