Step-by-step explanation:
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± 
( subtract 2 from both sides )
x = - 2 ±
Thus
x = - 2 - ≈ - 5.32 ( to 2 dec. places )
x = - 2 + ≈ 1.32 ( to 2 dec. places )
Answer:
i think it's c
Step-by-step explanation:
ok so i think i get it, volume is width*length*depth so dividing the known volume by its width gives you the length*depth.
after that set up a porportion:
(L*W)of known/92 = x/46
solve for x gives you the length*depth of the unknown volume, times that but the 46 width.. i got 60
i think that's right but im not a teacher or anything
8/12 4/8 4/12 is the answer for the shaded part
