0.25x2 -0.25x - 10.5 = 0<br><br>​
Tpy6a [65]

x=7 or x=-6

Let's solve your equation step-by-step.

0.25x2−0.25x−10.5=0

For this equation: a=0.25, b=-0.25, c=-10.5

0.25x2+−0.25x+−10.5=0

Step 1: Use quadratic formula with a=0.25, b=-0.25, c=-10.5.

x=

−b±√b2−4ac

2a

x=

−(−0.25)±√(−0.25)2−4(0.25)(−10.5)

2(0.25)

x=

0.25±√10.5625

0.5

x=7,−6

In a Healthy Jogging event, a few hundred participants were expected to jog 4 000 000 metres altogether. They had jogged 69 000
maks197457 [2]

The hundreds that must be added to 69,000 to make 4,000,000 is 39.

<h3>What does division mean?</h3>

Division is a mathematical operation that involves dividing a number into equal parts using another number. The sign used to denote division is ÷.

<h3>How many hundreds must be added to 69,000 to make 4,000,000?</h3>

In order to determine the answer, divide 4,000,000 by 100,000: 4,000,000 / 100,0000 = 40.

Because 69,000 has already been ran, subtract 1 from 40. This gives 39.
