Answer:
Using distribute property
0.5(8a)(a) + 0.5(6b)(a) + 4b
4a^2 + 3ab + 4b
Step-by-step explanation:
To find the cost of one book you need to divide 40.20 by 3.
40.20/3= 13.4
Dont forget the dollar sign - $13.4
Cost of one book is $13.4
1 Simplify n+5+-m-3n+8n+5+−m−3n+8 to n+5-m-3n+8n+5−m−3n+8.
11-2m-(n+5-m-3n+8)11−2m−(n+5−m−3n+8)
2 Collect like terms.
11-2m-((n-3n)+(5+8)-m)11−2m−((n−3n)+(5+8)−m)
3 Simplify (n-3n)+(5+8)-m(n−3n)+(5+8)−m to -2n+13-m−2n+13−m.
11-2m-(-2n+13-m)11−2m−(−2n+13−m)
4 Remove parentheses.
11-2m+2n-13+m11−2m+2n−13+m
5 Collect like terms.
(11-13)+(-2m+m)+2n(11−13)+(−2m+m)+2n
6 Simplify.
-2-m+2n that is the answer plz Mark me brainliest:)
