Question

Priya’s class has adopted two equal sections of a highway to keep clean. The combined length is 34 of a mile. How long is each section?

Answer 1

Step-by-step explanation:

x-1/x= 3

[x(square)-1]x= 3

x(square)-1= 3x

x(square)-3x-1= 0

a=1

b=-3

c=-1

Quadratic Formula

D=b(square)-4ac

D= 3^2 - 4(1)(-1)

D= 9 +4

D= 13

[ -b+-(plusminus)(D)] / 2a

use the formula and u will get the answer
