Step-by-step explanation:
hope it helps
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:)
This question is a little vague..Please rephrase your question :D
Answer:
<h2>A = 60 in²</h2><h2 />
Step-by-step explanation:
a = 12 in
b = 8 in.
h = 6 in.
<u>plugin values into the formula:</u>
A = 1/2 h(a + b)
A = <u>(12 + 8) </u> x 6
2
A = 60 in²
