Answer:

x=-1-i\sqrt{7}, -1+i\sqrt{7}

Step-by-step explanation:

x=\frac{-b+\sqrt{b^2-4ac} }{2a}

x=\frac{-b-\sqrt{b^2-4ac} }{2a}

Here a=1, b=2 and c=8

barxatty [35]
To solve this problem you have to convert the percentage to a decimal which would
be .40.

40% =40/100=.40


After doing so all you need to do is divide the amount needed by the percentage which gives you the amount she has saved.

225/.40= $90

Lauren has $90 saved

BRAINLIEST AND 50 POINTS
lilavasa [31]

Answer:

P ( blue ) =  1/4

P ( white ) =  5/12

P ( red ) = 1/3

P ( not red ) =  2/3

Step-by-step explanation:

To find the probability of a marble being chosen,  it is the number of that color over the total

We need to find the total number of marbles

4 red+ 5 white+3 blue = 12 marbles

P ( blue ) = 3 blue / 12 total = 3/12 = 1/4

P ( white ) = 5 white / 12 total = 5/12

P ( red ) = 4 red/ 12 total = 4/12 = 1/3


How man marbles are not red

total marbles - red marbles = 12-4 = 8

8 marbles are not red

P ( not red ) = 8 not red / 12 total = 8/12 = 2/3

How to find upper and lower bound of a definite integral given an unknown equation?
worty [1.4K]
Finding the upper and lower bounds for a definite integral without an equation is pretty hard because how can we find the upper and lower bounds of  definite integral if there is no equation given. But I will teach you how to find the lower and upper bounds of a definite integral, when the equation is like this 

\int\limits^6_1 t^{2} - 6t + 11dt 

So, i integrate this, 
( \frac{t^{3} }{3} - 3t^{2} + 11t) \int\limits^6_1

I know I have a minimum at x=3 because;
f(t )= t^2 − 6t + 11
f′(t) = 2
t−6 = 0
2(t−3) = 0
t = 3
f(5) = 4
f(1) = −4
