Solve x2 - 8x + 3 = 0 by completing the square. Which equation is used in the process?

(x - 4)2 = 0

(x - 4)2 = 13

(x - 4)2 = 19

The correct answer for this would be the second option. The equation that is used in the process in completing the square is this: (x - 4)2 = 13.

The solution is this:

(x-4)(x-4) = 13

x^2 - 4x - 4x + 16 = 13

x^2 - 8x +16 = 13

x^2 - 8x = 13 -16

x^2 - 8x = -3

x^2 - 8x + 3 = 0

Hope this answers your question. Have a great day!

The solution is this:

(x-4)(x-4) = 13

x^2 - 4x - 4x + 16 = 13

x^2 - 8x +16 = 13

x^2 - 8x = 13 -16

x^2 - 8x = -3

x^2 - 8x + 3 = 0

Hope this answers your question. Have a great day!

Answer:

the correct answer is (x - 4)2 = 13.

How do you write 6.6 (terminating) as a fraction?

6 3/5

6.6 is equal to 6 and 6/10

from there we just simplify 6/10 to 3/5

this is called a mixed number

or you could have an improper fraction which is 66/10,its where the numerator exceeds the denominator.

A crew will arrive in one week and begin filming a city for a movie. The mayor is desperate to clean the city streets before filming begins. Two teams are available, one that requires 200 hours and one that requires "400" hours. If the teams work together, how long will it take to clean all of the streets? Is this enough time before the cameras begin rolling?

Answer:

See below in bold.

Step-by-step explanation:

You work in fractions of the city streets done per hour:

1/200 + 1/400 = 1 /x where x is the number of hours taken by 2 teams.

Multiply through by the LCM 400x:

2x + x = 400

3x = 400

x = 133.33 hours.

As there are 168 hours in a week they will have enough time.
