420!

840 x (3/7) = 360
840-360 = 480
480 x (1/8) = 60
480 - 60 = 420

If the discriminant of a quadratic function is positive, then the quadratic function has two real solutions

If the discriminant of a quadratic function is zero, then the quadratic function has one real solution

If the discriminant of a quadratic function is negative, then the quadratic function has two complex solutions

In this problem

The quadratic function has two real solutions (x-intercepts)

therefore

The discriminant is positive

a segment is divided into two parts having lengths in the ratio of 5:3. if the difference between the lengths of the parts is 6

iren [92.7K]

2 parts.....ratio is 5:3...added = 8.....so one of the parts is 5/8 of the total...5/8x....and the other part is 3/8 of the total...3/8x

the difference is 6...
5/8x - 3/8x = 6
2/8x = 6
x = 6 * 8/2
x = 48/2
x = 24

so the total length is 24
with the longest being : 5/8(24) = 15 <==
and the shortest being : 3/8(24) = 9
