Answer: OPTION C

Step-by-step explanation:

Complete the square:

Having the equation in the form ax^2+bx=c, you need to add (\frac{b}{2})^2 to both sides of the equation:

You can identify that "b" in the equation x^2+6x=5 is:

b=6

Then:

(\frac{6}{2})^2=3^2

Add this to both sides:

x^2+6x+3^2=5+3^2

Rewriting, you get:

(x+3)^2=14

Solve for "x":

 x+3=\±\sqrt{14}\\\\x+3=\±\sqrt{14}\\\\x=\±\sqrt{14}-3

Then, the solutions are:

x=-3+\sqrt{14}\ or\ x=-3-\sqrt{14}

Maria needs to reach a window that is eight feet above the ground. When she placed a ladder so that it reached the bottom of the
mr_godi [17]

Answer:

10 feet

Step-by-step explanation:

Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.

The length of the ladder represents the hypotenuse side hence using pythagoras theorem

F^2 = 8^2 + 6^2

where F is the length of the ladder in feet

F^2 = 64 + 36

= 100

find the root of both sides

F = 10 feet

The ladder is 10 feet long
