Answer:
6.3
Step-by-step explanation:
Multiply: .7 X 1= .7 and 0.55 X 2= 1.1
Add: 4.5 + .7 + 1.1 = 6.3
To do this, we need to use the distributive property. The distributive property allows the outside number of a parenthesis to multiple all numbers within the parenthesis. Let's use this formula and break it down.
-2n(4n-2) = -2n(4n) + -2n(-2)
-2n(4n) = -8n^2
-2n(-2) = 4n
Our expression is now -8n^2 + 4n.
