2+2=4 so now its 4/4*10. 4*10 is 40 so now its 4/40. Dividing both sides by 4 will get you the simplest form 1/10
the first one is -11,-5,2,6,19
The less coefficient in front of x^2, the wider graph
the smallest coefficient is 1/5 , so the widest graph is y=(1/5)x²
The simplification of 3log(x + 4) – 2log(x – 7) + 5log(x - 2) - log(x^2) is 
<u>Solution:</u>
Given, expression is 
We have to write in as single logarithm by simplifying it.
Now, take the given expression.

Rearranging the terms we get,







Hence, the simplified form
