80 divided into 4356 should be around 48.94
Answer:
-5/3
Step-by-step explanation:
(3x+5)(3x+5) is the factored form of the quadratic: 9x^2+30x+25
In equation form, it will be 9x^2+30x+25 = 0 so we have:
(3x+5)(3x+5) = 0
To solve these types of equations, we find the roots. Since the product of these numbers is 0, (3x+5) has to be equal to 0.
3x + 5 = 0
Subtract 5
3x = -5
Divide by 3
x = -5/3
Answer:
x=574

<span>the balanced net ionic equation for the precipitate reaction
</span>
Na2SO4 + Ba(NO3)2 -------------> <span>BaSO4 + Na2(NO3)2
</span><span>the number of moles of sulfate in the sample
M = m /n
M molar mass
m mass
n number of moles
so n =m/M
n = 8.642/233.33=0.037mol
