Hence, the correct answer is: C) (x - 6)^2 = 45

Further explanation:

Given equation is:

x^2-12x-9=0

We will move the constant term on other side of the equation

x^2-12x=9

To complete the square, we will take the coefficient of x and divide it by 2, as we already know that one term is x.

\frac{12}{2}=6

So, adding (6)^2 on both sides

(x)^2-2.x.6+(6)^2=9+(6)^2\\(x-6)^2=9+36\\(x-6)^2=45

Hence, the correct answer is: C) (x - 6)^2 = 45

Help pls I got the other one wrong and my score went down :( PLS HELP ME NOW ITS PYTHAGOREAN THEOREM
vovangra [49]

Answer:

9.4

Step-by-step explanation:

We can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2+8^2 = c^2

25 +64 = c^2

89 = c^2

Taking the square root of each side

sqrt(89) = sqrt(c^2)

9.433981132 = c

To the nearest tenth
