Answer:

A. -9n + 20

Step-by-step explanation:

First, distribute -5 to all terms within the parenthesis:

-5(2n - 4) + n

(-5 * 2n) + (-5 * -4) + n

-10n + 20 + n

Simplify. Combine like terms:

(-10n + n) + 20

(-9n) + 20

A. -9n + 20 is your answer.

Factor the expression using distributive property: 72b + 45

ANTONII [103]

The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!

Hope this helped! :D
