In this question , we have to simplify the given ratio, which is
12xy:3x
First we have to see which factor is common in numerator and denominator,
We can write 12 as 3 times 4, that is
So the common factor is 3x.
In the next step, we cancel out 3x
And that's the required simplified form .
I hope this helps....
x=-2
g(-2)= 3(-2)-2
= -6-2
g(-2)= -8
x=0
g(0)= 3(0)-2
=-2
x=5
g(5)=3(5)-2
g(5)=13
