O 3g + 5h
The simplified form of 9g7h-6g+2h is 3g + 5h.
To simplify the expression 9g7h - 6g + 2h, we can combine like terms.
The term 9g7h does not have any like terms, so it remains as is.
The terms -6g and 2h are like terms as they both have no coefficient on the g term (the coefficient is understood to be 1).
Therefore, combining the like terms -6g and 2h gives us -6g + 2h.
Putting it all together, the simplified expression is 9g7h - 6g + 2h can be simplified to 9g7h - 6g + 2h.
To simplify the given expression, you need to combine like terms. Like terms are terms that have the same variables raised to the same powers.
In the expression 9g7h - 6g + 2h, the only like terms are the terms involving g and h.
Let's start with the terms involving g: 9g7h and -6g. To combine these terms, you add their coefficients:
9g7h - 6g = (9g7h) + (-6g) = 9g7h - 6g.
Now, let's move on to the terms involving h: 9g7h and 2h. Again, you add their coefficients:
9g7h + 2h = 9g7h + 2h.
Combining these results, we have:
9g7h - 6g + 2h = 9g7h - 6g + 2h.
Therefore, the simplified expression is 9g7h - 6g + 2h, and none of the options provided (3g - 5h, 2gh - 4gh, -2gh, 3g + 5h) represent the simplified form.
