Answer:THXXXXXXXSSSSS FOR THE POINTS
Step-by-step explanation:
Answer:
{ - 2, 10 }
Step-by-step explanation:
Given
x² - 8x = 20
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = 20 + 16, that is
(x - 4)² = 36 ( take the square root of both sides )
x - 4 = ± 
= ± 6 ( add 4 to both sides )
x = 4 ± 6
Thus
x = 4 - 6 = - 2
x = 4 + 6 = 10
So, 3.55 g of copper could be made from 4 g of copper oxide.
The formula for copper oxide to convert to copper is a chemical equation Cupric oxide, or copper (II) oxide, is an inorganic compound with the chemical formula CuO.

Answer:
Step-by-step explanation:
3⅔ = 11/3
1¼ = 5/4
length = area ÷ width
= (11/3) ÷ (5/4)
= (11/3) × (4/5)
= 44/15
= 2 14/15 inches
