Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
The growth of the population can be expected to be about 3000 a year, so for the youer 2020 the figure 53 000 is the closest 33000 + 7 x 3000 = 54 000SHOW FULL ANSWER

Answer:
40 square inches
step-by-step explanation:
The new club sticker is in the shape of a triangle
It has a height of 8 inches
And a base of 10 inches
Area of a triangle is given by: 
× base × height
Area of the triangular club sticker = × 10 inches × 8 inches = 40 square inches.
An= -16 + (n-1)7
an= -16 + 7n - 7
an=7n -23
When the rate of change is 7
{a1 = 16, a2=-9, so the rate of rate of change is 7}
