Simplify
7m² + 6.5n -4n + 2.5m²
My answer is 9.5m² + 1.5n
BRUH YOUR 4 YEARS LATE TO THIS
Not bad, except that 6.5-4 ≠ 1.5
steve he forget to add the - n at the end
To simplify the expression 7m² + 6.5n - 4n + 2.5m², you can combine like terms. Like terms are terms that have the same variables raised to the same powers.
Starting with the terms that have "m", we have 7m² + 2.5m². Since they have the same variable "m" raised to the same power (²), you can add their coefficients together. Adding 7 and 2.5 gives you 9.5, so the combined term is 9.5m².
Next, let's consider the terms that have "n". We have 6.5n - 4n. These two terms have the same variable "n", so we can subtract the coefficients. Subtracting 4 from 6.5 gives you 2.5, so the combined term is 2.5n.
Therefore, the simplified expression is 9.5m² + 2.5n.
