Answer:
If you just solve normally, you will get x=2 and x=-3. But if you plug these in to check your work, you will find that they are wrong. Your answer is no solution
Step-by-step explanation:
ln(2x+3)+ln(x-2)=ln(x^2-2x)
<em>Rule: log(a) + log(b) = log(a*b)</em>
ln( (2x+3)(x-2) ) = ln(x^2-2x)
<em>Rule: If log(a) = log(b) then a = b</em>
(2x+3)(x-2) = x^2 - 2x
2x^2-x-6=x^2-2x
x^2+x-6=0
<em>Using Quadratic Formula:</em>
x = 2 and x = -3
But, plugging these numbers back into the original equation is false!
Answer:
Step-by-step explanation:
The given equation is :
Where
P is pressure
V is volume
n is no of moles
r is Gas constant
T is temperature
We need to solve the above equation for r.
Dividing both sides of the above equation by (nT). So,
So, the value of r is equal to 
.
The answer for question is 5400
Answer:
a=8cm
Step-by-step explanation:
Because the triangles are similar, you can set the sides to be proportional
1. 16/16=8/a
2. If you cross multiply that mean that a=8
