Find the difference.<br>(2n - 9) - 5(-2.4n + 4) =​
MArishka [77]

Answer:

14n - 29

Step-by-step explanation:

First you'd distribute in the parentheses by -5. -5 × -2.4n and -5 × 4 which you would get 12 and -20.

Then, bring everything down and combine like terms. 2n + 12n = 14n || -9 - 20 or -9 - (-20) = -29. 14n - 29 is the lowest you can simplify because you can subtract a variable and a constant together.
