Answer:

  x = -4/3  or  3/4

Step-by-step explanation:

To solve the equation by completing the square, it is convenient to have the leading coefficient be 1. Accordingly, we divide the equation by 12:

  x^2 +7/12x -1 = 0

Add the constant.

  x^2 +7/12x = 1

Add the square of half the x-coefficient.

  x^2 +7/12x +49/576 = 1 +49/576

Write the left side as a square; simplify the right side.

  (x +7/24)^2 = 625/576

Take the square root.

  x +7/24 = ±25/24

  x = (-7 ±25)/24

  x = -4/3  or  3/4

_____

These solutions suggest the equation could be factored as ...

  (3x +4)(4x -3) = -0

Evgen [1.6K]

To calculate this we should firstly calculate that how many laps can he do in an hour. So assuming that he does all the laps at the same rate he must do 120 laps in an hour.

Now because he burns 1200 calories per hour we can see how many number of hours it would take him to burn 15000 calories. So it would take him around 15000 / 1200 = 12.5 hours. So now we will multiply 12.5 by 120 laps as that is the number laps he can do in an hour. So that is around 1500 laps a day.

Murljashka [212]

Answer:

The answer is 9.

Step-by-step explanation:

The degree of a monomial is defined as the sum of all the exponents of the variables, including the implicit exponents of 1 for the variables which appear without exponent.

<u>In this case, we will add 2, 6, and 1.</u>

2 + 6 + 1 = 9
