Step-by-step explanation:
5x² + 5x + 3 = 0 ← in standard form
with a = 5 , b = 5 , c = 3
Solve using the quadratic formula
x = ![\frac{-b+/-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%2B%2F-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
= ![\frac{-5+/-\sqrt{5^2-(4(5)(3)} }{2(5)}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%2B%2F-%5Csqrt%7B5%5E2-%284%285%29%283%29%7D%20%7D%7B2%285%29%7D)
= ![\frac{-5+/-\sqrt{25-60} }{10}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%2B%2F-%5Csqrt%7B25-60%7D%20%7D%7B10%7D)
= ![\frac{-5+/-\sqrt{-35} }{10}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%2B%2F-%5Csqrt%7B-35%7D%20%7D%7B10%7D)
= ![\frac{-5+/-\sqrt{-1(35)} }{10}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%2B%2F-%5Csqrt%7B-1%2835%29%7D%20%7D%7B10%7D)
= ![\frac{-5+/-i\sqrt{35} }{10}](https://tex.z-dn.net/?f=%5Cfrac%7B-5%2B%2F-i%5Csqrt%7B35%7D%20%7D%7B10%7D)
Then
x =

, that is
x = -

Answer:
9 containers
Step-by-step explanation:
115/12.4= 9.27
9 possible containers
Okay So the Y intercept is 4 because the line passes through the y-axis and makes contact at 4. The Slope is 1/2 because You go down 1 and over 2 to get to the next point the connects to the next corner so the Slope Intercept Equation is Y=1/2x + 4
176 in The area of the first square is 44 and you want to find the second square you will have to do 44*4=176
