Answer:
Mr. Porter's claim was not correct and it will be a 21% increment.
Step-by-step explanation:
The value of the house when Mr. Porter bought the house was d.
The present value of the house is given by d + 0.21d = 1.21d.
Hence, the increase in the value of the house is 0.21 d and the final value of the house is 1.21d.
So, if Mr. Porter claims that the value of his house has increased by 121%, then his claim is wrong. The increase in value is only by 0.21d i.e. by 21% and after this increment, the value becomes 1.21d i.e. 121%.
Therefore, his claim is not correct and it will be a 21% increment. (Answer)
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:)
