Answer:
h < 14
Step-by-step explanation:
2h +8 > 3h - 6
2h - 3h > - 6 - 8
-h > -14 (multiply both sides by -1; remember to flip the inequality sign!)
h < 14
Answer:
Step-by-step explanation:
2x² -x - 6 = 2x² - 4x + 3x - 3*2
= 2x*(x - 2) + 3*(x - 2)
= (x-2)(2x + 3)
A = 2x² -x - 6
A = (x - 2)(2x + 3)
length*width = (x - 2)(2x + 3)
length * (2x +3) = (x - 2)(2x + 3)

length = x - 2
5 billion * ( 1 + 0.013 ) ^x = 10 billion
1.013 ^x = 10 : 5 = 2

x = 54
1986 + 54 = 2040
In the year 2040 the world`s population will be 10 billion.
