Salma drove 605 miles in 11 hours at the same rate how long would it take her to drive 385

divide 605 by 11 to find her speed

605/11 = 55 ( she drove 55 miles per hour )

 now divide 385 by 55 to find time

385/55 = 7 hours

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
