You have to tell them what you think would happen to the earth if the sun disappeared.<span />
Answer: a=5+√5
b=5-√5
Step-by-step explanation:
a=?
b=?
P=20
A=20
P=a*b=20
A=a+b=20
------------------
ab=20
a+b=10
--------
a=10-b
(10-b)b=20
-b²+10b-20=0
b=-10±√100-80/-2
b=-10±√20/-2
b=-10±2√5/-2
b=-10-2√5/-2=5+√55
b=5-√5
a+b=10
a+5-√5=10
a=5+√5
a+5+√5=10
a=5-√5
We are given with the set <span>K with members: 2, 4, 2, 0, 6, 0, 10, 8. The correct expression of set here is { 0 , 2 , 4 , 6, 8, 10 }. The numbers repeated are represented by one number in the set where the members are also arranged in order. </span>
