Answer:
D is correct. ( 4m - 5 ) + ( -6m + 7 - 2n )
Step-by-step explanation:
We are given a difference of two polynomial
(4m-5) - (6m-7+2n)
We need to choose correct choice which is equivalent to given expression.
Here we have minus sign between two parentheses.
First we distribute minus sign over (6m-7+2n) using distributive property.
Minus sign will distribute with each term inside (6m-7+2n).
When it will distribute it changes the sign of each term inside the parentheses.



After distribution we get
( 4m - 5 ) + ( -6m + 7 - 2n )
Thus, D is correct option which is similar to given expression.
2.2 , 2.25, .4, 2.8
Order from least to greatest is
.4 2.2 2.25 2.8
