Answer:
x = -0.17 and x = -5.83
Step-by-step explanation:
We are asked to solve the quadratic equation
![x^2+6\,x+1=0](https://tex.z-dn.net/?f=x%5E2%2B6%5C%2Cx%2B1%3D0)
We use the quadratic formula using a = 1, b = 6 and c = 1
for a general quadratic equation of the form: ![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
Then, the solutions are given by;
![x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-6%2B%2F-%5Csqrt%7B36-4%5C%2C%281%29%5C%2C%281%29%7D%20%7D%7B2%7D%20%3D%5Cfrac%7B-6%2B%2F-%5Csqrt%7B32%7D%20%7D%7B2%7D)
which produces the two following answers (rounded to two decimals):
x = -0.17 and x = -5.83

X + y = 12 . . . . . . . . (1)
x - 3y = -30 . . . . . . . (2)
(1) - (2): 4y = 42
y = 10.5
44 / 3 2/3 = 12
the missing length (x) = 12
Answer:
Choice D
Step-by-step explanation:
(x-1)²
- =(x-1)(x-1)
- =x*x+x*−1+-1*x+-1*-1
- =x²−x−x+1
- =x²−2x+1
Choice D is accurate.

Answer:
e.29 d.1
Step-by-step explanation:
we will replace with the values we have :
- 300 that's a big number . Obviously it isn't a solution
- 50 : 30+50 = 80>60 so no
- 45: 30+45= 75 >60 so no
- 30+30 = 60 we have < not ≤ so no
- 1 yes . it's obvious
- 29 +30 = 59<60 so yes !
