Answer:
x = 3 ± i 
Step-by-step explanation:
Given
x² - 6x + 12 = 0 ( subtract 12 from both sides )
x² - 6x = - 12
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = - 12 + 9
(x - 3)² = - 3 ( take the square root of both sides )
x - 3 = ±
= ± i
( add 3 to both sides )
x = 3 ± i 
You could only make 4, as that is half of the amount of materials needed to make 8.
Answer:
4f + 6g -5
Step-by-step explanation:
4f - 3 +2g- - 4g + 2
4f - 3+ 2g + 4g - 2
4f -3-2 +2g +4g
4f -5 + 6g
4f + 6g -5
Lwh=v
2*w*(w+2)=48
2w^2+4w=48
w^2+2w-24=0
(w+6)(w-4)=0
w= - 6 or w= 4
Since w cannot be negative, then w=4.
