Answer: Our required values would be -10x+5, 2x+5 and -25.
Step-by-step explanation:
Since we have given that
g(x) = -4x+5
and
h(x) = 6x
We need to find (g-h)(x) and (g+h)(x).
So, (g-h)(x) is given by

and (g+h)(x) is given by

and (g-h)(3) is given by

Hence, our required values would be -10x+5, 2x+5 and -25.
No, without further information you can't tell which number is greater. This is because there could be any amount of other digits to the right, which changes the value of the leftmost digit depending on the number it is a part of.
Hope this helps! :)
