Answer:

see the explanation

Step-by-step explanation:

we know that

A <u>Rational Number</u> is a number that can be made by dividing two integers

we have

\frac{\sqrt{2}}{8}

\sqrt{2} ----> is not a integer

so

The given number cannot be rewritten as the quotient of two integers

therefore

The given number is irrational

Student A is incorrect because is a irrational number and not all fractions are rational

Student B reasoning is incorrect, because there are fractions that have as numerator an irrational number and can be rational numbers

<em>example</em>

\frac{\sqrt{2}}{3\sqrt{2}}=\frac{1}{3} ----> is a rational number and the numerator is a irrational number

3 times a number is 54 less than the square of that number. Find the negative solution.
Pavel [41]

Answer:

x=-6

Step-by-step explanation:

Let x be the number

3x = x^2 -54

Subtract 3x

3x-3x = x^2 -3x-54

0 = x^2 -3x-54

Factor

What 2 numbers multiply to -54 and add to -3

-9*6 = -54

-9+6 = -3

0=(x-9) (x+6)

Using the zero product property

x-9=0    x+6=0

x=9  x=-6

The questions asks for the negative solution

x=-6
