Answer:
x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11
Step-by-step explanation:
This polynomial is a quadratic. Its coefficients are a = 1, b = 1 and c = 3.
Thus, the discriminant b^2-4ac is 1^2 - 4(1)(3), or 1 - 12, or -11.
Because the discriminant is negative, the roots are complex.
The roots are:
-1 ±√(-11) -1 ±i√11
x = --------------- = ----------------, so x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11

Answer:
Cereal A is a better option
Step-by-step explanation: If someone were to buy a 14-ounce box of cereal for $4.20 <--(Cereal A) and another person wants to buy the 12-ounce box for $3.90 <-- (Cereal B)You need to find how much one ounce costs. So, you have to divided $4.20 by 14 and that gives you $0.30 and so you do the same for Cereal B, $3.90 by 12 that gives you $0.33. Which one is less cheaper? Cereal A
Answer:
x = 2
Step-by-step explanation:
6x - 5 = 13 – 3x
Add 3x to both sides
6x + 3x - 5 = 13 - 3x + 3x
9x - 5 = 13
Add 5 to both sides
9x - 5 + 5 = 13 + 5
9x = 13+5
9x = 18
Divide both sides by 9
9x/9 = 18/9
x = 2
