Answer:
x = -3±sqrt( 5)
Step-by-step explanation:
(x + 3)^2-5=0
Add 5 to each side
(x + 3)^2-5+5=0+5
(x + 3)^2 = 5
Take the square root of each side
sqrt((x + 3)^2 )=±sqrt( 5)
x+3 = ±sqrt( 5)
Subtract 3 from each side
x+3-3 = -3±sqrt( 5)
x = -3±sqrt( 5)
Answer:
Option (B) is correct.
The mass of the reactants equals the mass of the products.
Step-by-step explanation:
According to law of conservation of mass :
In a balanced chemical equation, the mass of reactants is always equal to the mass of products.
Here, Water
is the reactant which has 4 units of Hydrogen and 2 units of oxygen.
and
are products which also has 4 units 4 units of Hydrogen and 2 units of oxygen.
Thus, The mass of the reactants equals the mass of the products.
Thus, option (B) is correct.
Answer:
sorry
Step-by-step explanation:
I don't know what you want , do you want to know how to construct an inscribed angle or what
The slope-intercept form: y= mx + b
9x - 7y = -7 |subtract 9x from both sides
-7y = -9x - 7 |divide both sides by (-7)
y = 9/7x + 1
