PLEASE HELP ASAP! I need the answer for this question anyone ?

Alexxandr [17]

Answer:

A: sqrt(11)

B: 4.2

C: sqrt(26)

Step-by-step explanation:

First, 4^2 = 16

That means that sqrt 11 is smaller than 4.2 (a value greater than 4). This is because sqrt16>sqrt11.

Sqrt(26) is greater than sqrt(25) = 5. That means that it's greater than 4.2.

Hence, the order given above.

Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.

Answer:

x=9,-1 and $x^2+(-8)x=9$

Explanation:

we have been given with the quadratic equation $x^2-8x-9$

we compare the given quadratic equation with general quadratic equation

general quadratic is $ax^2+bx+c=0$

from given quadratic equation a=1,b= -8,c= -9

substituting these values in the formula for discriminant $D=b^{2}-4ac$

$D=(-8)^2-4(1)(-9)=100$

Now, to find the value of x

Formula is $x=\frac{-b\pm\sqrt{D}}{2a}$

Now, substituting the values we will get

$x=\frac{-(-8)\pm\sqrt{100}} {2}= \frac{8\pm10}{2}=9,-1$

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

$x^2+bx=c$
