Question 110303
Question:


use the distributiveproperty to removethe parentheses in the expression. Simplify by combining like terms.  7(4w-3)-25w


Answer:

7 ( 4w - 3 )- 25w

use the distributive property to remove the parentheses in the expression.


==> 7 *4w - 7* 3  - 25w



==> 28 w - 21 - 25w


Now combine the like terms( That is the terms which contain the same variable, here like terms are 28w and 25w)


==> 28 w - 25w - 21 



==> (28 w - 25w) - 21 


==> 3w - 21, 


Here you can simplify further by taking out the common term from both 


==> 3(w - 7 ), which is the simplified form


Hope you found the explanation useful.
