What is the simplified form of the following expression? 7m² + 6.5n -4n + 2.5m²
collect like terms
7 m^2 + 2,5 m^2 = how many m"2 s?
6.5 n - 4 n = how many n s ?
To simplify the expression 7m² + 6.5n - 4n + 2.5m², we can combine the like terms. Like terms have the same variables with the same exponents.
First, let's combine the terms with "m". We have 7m² and 2.5m². Since both terms have "m²", we can add the coefficients. 7m² + 2.5m² equals 9.5m².
Next, let's combine the terms with "n". We have 6.5n and -4n. Since both terms have "n", we can add the coefficients. 6.5n + (-4n) equals 2.5n.
Now we have simplified the expression to 9.5m² + 2.5n.
