Step-by-step explanation:
Answer:
x = -3.73 or -0.27
Step-by-step explanation:
From the question,
x²+ 4x+1 = 0
This is a quadratic equation, and it can be solved using any of the 3 methods.
Using completing the square method,
x²+4x = -1
Add half the coeffiecient of x, square it and add it to both side of the equation.
The coefficient of x is 4,
half the cofficient is 2
Add 2² to both side of the equation
x²+4x+2² = -1+2²
(x+2)² = 3
x+2 = ±√3
x+2 = ±1.73
Either,
x+2 = -1.73
x = -1.73-2
x = -3.73
or
x+2 = +1.73
x = =1.73-2
x = -0.27

Answer:</h2>
The time it will take Kelsey to paint the entire room is:
<h2>
Step-by-step explanation:</h2>
It is given that:
Kelsey painted one fourth of her bedroom in three seventh of an hour.
This means that:
1/4 of bedroom takes 3/7 of an hour
This means that the whole of the bedroom will take 4 times the time it took to cover 1/4 th of bedroom.
i.e. it will take:
Hence, the total time it will take to paint the whole room is:
twelve over seven hours
