Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- percent
- percentage words problem
- PEMDAS
<h3>given:</h3>
- population:2500
- decreasing rate:3%
<h3>to find:</h3>
- the population after 11 years
<h3>let's solve:</h3>
according to the question
population decreases in 1 year
population will decrease in 11 years
so the population of the town after 11 years will be
2500-825
<h2>1675</h2>

Answer:
x = 2
Step-by-step explanation:
3(5x - 2) + 1 = 25 (Given)
3(5x) + 3(-2) + 1 = 25 (Distributive Property of Equality)
15x + -6 + 1 = 25 (Simplify)
15x - 5 = 25 (Simplify)
15x + 5 + 5 = 25 + 5 (Addition Property of Equality)
15x = 30 (Simplify)
(Division Property of Equality)
x = 2 (Simplify)
For roots r1 and r2, the factors are (x-r1)(x-r2)
given
r1 and r2 arer 5+i√2 and 5-i√2
(x-(5+i√2))(x-(5-i√2))=
(x-5-i√2)(x-5+i√2)=
remember that i²=-1
x²-10x+27
