3x^2 + 11x - 4 = 0
Look for two factors of -12 that add up to 11 -> -1 and 12
(3x - 1)(x + 4) = 0
x = 1/3 or -4
So the answer you want is D

An easy way to answer questions like this is simply to try each option until one works.
3 x 0^2 + 11 x 0 = 0 so not A
3 x (-11/3)^2 + 11 x -11/3 = 0 so not B
3 x 4^2 + 11 x 4 = 92 so not C
3 x (1/3)^2 + 1 x 1/3 = 12/3 = 4 correct
I doubt E would be marked correct but in fact A and E are opposite statements so one of them must be true

In one day Sasha got 1 hour of sleep for every 3 hours she was awake if there are 24 hours in a day how many hours of sleep did
Gre4nikov [31]

Answer:

Hours slept = 6 hours

Hours awake = 18 hours

Step-by-step explanation:

Sasha got 1 hour of sleep for every 3 hours she was awake.

So,

<u>This means:</u>

Slept : Awake = 1 : 3

Total hours in a day = 24 hours

<u>Let </u>

Hours slept = 1x and hours awake = 3x

<u>Hence,</u>

1x + 3x = 24 hours

4x = 24

Divide both sides by 4

x = 24 / 4

x = 6

<u>So,</u>

Hours slept = 1(6) = 6 hours

Hours awake = 3(6) = 18 hours

\rule[225]{225}{2}

Hope this helped!
