What is the simplest form of the expression?
Stella [2.4K]
The answer is C. 4√5 

To calculate this, we must find the greatest common divisor of these 3 numbers √20,√45, and √5.
The greatest common divisor is √5:
\sqrt{20} = \sqrt{5*4} = \sqrt{5} * \sqrt{4} = \sqrt{5} *2= 2\sqrt{5}
\sqrt{45} = \sqrt{5*9} = \sqrt{5} * \sqrt{9}=\sqrt{5}*3 = 3\sqrt{5}

Therefore,
\sqrt{20} + \sqrt{45}- \sqrt{5}=2 \sqrt{5} +3\sqrt{5}-1\sqrt{5}=\sqrt{5}(2+3-1)=4\sqrt{5}

If f(x) = 3x²+2 and g(x)=x2-9, find (f- g)(x).
Solnce55 [7]

Answer:

Step-by-step explanation:

Depending on whether or not the g(x) is x^2 or 2x, I have both ways.

If g(x) is x^2 - 9...

--> (3x^2 + 2) - (x^2 - 9) = 2x^2 + 11

If g(x) is 2x...

--> (3x^2 + 2) - (2x - 9) = 3x^2 - 2x + 11

Hope this helps!
