When you're looking for the changes between the two, it is best to simply look for the differences. In this case, the first equation has a positive 4 included, whereas, the second doesn't.

Hope this helps :)

Answer:
Most ancient Egyptians were unlikely to live beyond 40 years of age and, for example, King Tutankhamun died at the age of about 18 years. This can be compared to today's life expectancy of 83 years for women and 79 years for men in the UK.

Answer:
AE = 30
GD = 5
GF = 10
Step-by-step explanation:
Centroid of medians divide median in the ratio 2 : 1
Therefore,
AG : GE : 2 : 1
Let AG = 2x & GE = x
Since, AG = 20....(given)
Therefore, 2x = 20
x = 20/2
x = 10
GE = x = 10
AE = AG + GE = 20 + 10 = 30
CG : GD : 2 : 1
Let CG = 2x & GD = x
Since, CG = 10....(given)
Therefore, 2x = 10
x = 10/2
x = 5
Since, GD = x
Therefore, GD = 5
BF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
