John ran 4 laps of the track in 5 minutes, 40 seconds

mihalych1998 [28]

Well, lets think about this. We need to ask our self how many seconds are in one minute. There are 60 seconds in 1 minute. We know he did 4 laps in 5 minutes and 40 seconds. You can change the minutes to seconds by multiplying 60 * 5 = 300 seconds. So 5 minutes = 300 seconds. Now just take the 40 seconds and add it to the 300 seconds, which will give you 340 seconds. So John ran 4 laps in 340 seconds. B wants to know how many seconds it took John per lap...We can find this by dividing 340 by 4 340/4 = 85.

A) 340 seconds

B) 85 sec/lap

The Quadratic Formula, x equals negative b plus or minus the square root of b squared minus 4 times a times c, all over 2 times

DedPeter [7]

Answer:

The correct option is 2 .

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is  2 . 

$x=\dfrac{4\pm\sqrt{2}}{2}$

Step-by-step explanation:

For a Quadratic Equation ax² + bx + c = 0

By Formula Method we get

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

So we have Quadratic Equation is 2x² - 8x + 7 = 0

On Comparing we get

$a=2\\b=-8\\c=7$

Substituting a , b, c values we get

$x=\dfrac{-(-8)\pm\sqrt{(-8)^{2}-4(2)(7)}}{2(2)}\\\\x=\dfrac{8\pm\sqrt{64-56}}{4}\\\\x=\dfrac{8\pm\sqrt{8}}{4}\\\\x=\dfrac{8\pm2\sqrt{2}}{4}\\\\x=2(\dfrac{4\pm\sqrt{2}}{4})\\\\x=\dfrac{4\pm\sqrt{2}}{2}$

Therefore ,the missing denominator of the solution. 4 plus or minus the square root of 2, all over is  2 .
